ADEO deorbit sail system from HPS

Space-related technologies should be clean and sustainable, because only then access to space will remain possible for future generations. This topic, which is currently a top priority of space policy, has led to a number of technical solutions which are now available on the market, with the ADEO deorbit system from HPS leading the way. Being recognized even by NASA, the ADEO dragsails ensure already before launch that satellites will not turn into space debris at the „end-of-business“. Instead, they re-enter the Earth’s atmosphere.

The European Space Agency ESA, as well as its national counterpart DLR and the Bavarian Ministry of Economic Affairs, has consistently supported the twelve years of development of this product by HPS. The sharp increase in demand from customers, particularly in the CubeSat and SmallSat sector from Europe, but also from North America and even Asia, is driven by the simple fact that both ESA, for European launches, and the FCC, for American launches, now demand on-board systems to be able to deorbit a satellite in just 5 years instead of the previous 25 years. Also SpaceX confirms that no more satellites will be launched without complying to this requirement.

With the ADEO variants “Pico”, “Cube”, “Nano”, “Medium” and “Large”, HPS meets the market demand for all sizes of LEO satellites in orbits between 300 and 900 kilometers. All variants are already in production, with manufacturing at the HPS production sites in Munich (Germany) and Bucharest (Romania) which are closely working together. Nevertheless, HPS and the technical ADEO experts at ESA have identified a number of optimization and expansion opportunities in order to urgently increase the pace of the series production and in response to the increasing price pressure of the New Space scene. The company is now raising the required funds for the implementation of these opportunities in the short term, using co-financing of 1.2 million euros signed by ESA on June 28, 2024.

ESA-Director Dietmar Pilz for Technology, Engineering and Quality in a videocon on July 1st: „my best wishes for this important technology development.“

HPS CEO Ernst K. Pfeiffer: “As a company, we are very pleased about the trust and continuous support from the European Space Agency, and therefore indirectly also from the German Ministry of Economic Affairs. However, this is at least as much a reason for joy for all those who, thanks to its technology programs such as GSTP, would like to see Europe in a leading role in the development of components for space technology and -transport, especially in the commercially so important LEO and MEO supplier market.

ESA’s priorities here are not only clear, but are also being consistently implemented. One milestone was the recent signing of the Zero Debris Charter in Berlin. The upcoming optimization of series production and the enhancement of our ADEO product portfolio, while maintaining the same level of quality and reliability, will effectively help to face the upcoming peaks in global orders, including those received very late, and thus still enable the launch of these satellites. We shareholders see our own funds, in the 7-digit range over the years, on the one hand as an investment in a strong future for HPS, and on the other hand as our moral obligation to make a contribution to the sustainable use of space.”

ESA Leads the Way: Rapid Implementation of the Zero Debris Charter

Sustainability in space travel has also been an issue for the European Space Agency ESA for years. However, only a few months passed between the decision to adopt a Zero Debris Charter and its implementation.

Keynote speaker ESA Director General Josef Aschbacher also saw this as a sign that the time is finally ripe for concrete steps instead of pure symbolism, especially as ESA itself has provided significant impetus for the development of the two main technologies on the way to “Zero Debris”: firstly, ways of removing scrap from space, but above all, equipping satellites with deorbit technology from the outset so that no more waste is produced after the end of the mission.

ADEO Drag Sail: The Key to Sustainable Spaceflight

The ADEO brake sail, which is now available as an entire product family for all sizes of LEO satellites from HPS series production, stands for this. In addition to grants and support from ESA, DLR and Bavaria, HPS CEO Ernst K. Pfeiffer also invested a lot of the company’s own money in the project, always firmly convinced that the hour of ADEO would come sooner or later – and if a little later, then all the more powerfully.

It was exactly the same when, in mid-2023, the ESA set the new rule of a deorbit maximum of 5 years for ESA-funded missions instead of the previous 25 years, and, accordingly, LEO satellites without ADEO (or similar) will no longer be launched at all from October 2024, as SpaceX, for example, makes clear in its conditions of carriage in accordance with FCC regulations.

Historic Moment: 12 Nations Sign the Zero Debris Charter

The Charter was signed in Brussels on May 22 by 12 countries, including Germany. Since then, over 100 organizations, companies and entrepreneurs have been waiting for their cue to sign.

The ILA 2024 marks a very important stage on this path towards the sustainability of European space travel and sets an example for companies on other continents.

KEAN II passes the acid test at the University of the German Armed Forces and in the field

KEAN, the integrated deployable lightweight manpack complete antenna from HPS and its development partners, has taken a decisive step forward in the KEAN II (Second Generation) version: it passed the tough link test at the University of the German Armed Forces in Munich in December 2023 and the handling test in the field. This brings the goal of the joint HPS project much closer: the development of a complete system for bidirectional satellite communication based on preliminary developments already carried out by HPS and these specifications:

• Conformance to satellite operators (e.g. EUTELSAT, INTELSAT)
• Ku-band, 1.2 m diameter, also X- and Ka-band capable
• Including communication system, electronics, battery, tripod, backpack carrying system
• Total weight <20 kg
• Commissioning in under 15 minutes from backpack transport to satellite link
• Innovative, cybernetic folding mechanism based on the opening and closing of flowers
• Design and definition of components and production processes suitable for series production for a rapid transition to series production in large quantities.

Partners in the project are:

• The system supplier MTEX (Wiesbaden) with a focus on ground stations and electronics.
• The start-up Blackwave (Ottobrunn) with the economical series production of complex carbon components.
• The Chair of Carbon Composites (LCC) at the Technical University of Munich for the design of innovative extremely lightweight reflector fins.
• The Bundeswehr University for defining the user requirements and carrying out the antenna link tests with satellites.

The additional antenna deployment tests in rough terrain in the Bavarian Alps were closely monitored from the air by camera-guided drones; they provided complete documentation of the challenges, but also of the success of these tests. Videos are available at the YouTube Channel. Particular attention was paid to features and elements such as these during the tests:

1. Wearing comfort off-road (walking and running) with different body sizes
2. Assembly and disassembly over time in rough terrain (bushes, gravel, snow)
3. Speed of unfolding and folding
4. Handling by untrained test persons
5. Wind load compatibility
6. Handling in cold conditions (requirement: from -30o C to +55 o C)
7. Robust construction

The target markets for applications of this completely new technology for communication via satellite, especially on X-, Ku- and Ka-band, cover all three conceivable directions:

• commercial, such as journalistic reporting from rough terrain
• institutional, such as rescue and disaster relief operations
• military, such as for small special forces operating independently of vehicles without a direct connection to the base of fully equipped large units
• scalable up to 3.6 m, also for mobile transportation on small vehicles.

Beyond the technical successes, KEAN II is currently growing wings from a completely different direction: the European Commission’s major IRIS2 project to establish absolutely secure connectivity via a dedicated multi-orbit constellation of several hundred satellites from LEO to GEO is giving a significant boost to all those application scenarios that were previously considered to have only seen very hesitant development due to their dependence on non-European constellations and individual satellites. This applies in particular to the institutional and military markets, both of which are now growing into larger dimensions.

The last stage of development was funded by the German Aerospace Center (DLR) as part of the ILKA project with funds from the Federal Ministry of Economics and Climate on the basis of a decision taken by the German Bundestag.

Servicing Europe´s ambitions in space from Romania

In less than a blink of an eye, it will be a full decade that Romania´s leading space-SME “High Performance Structures Inovatie si Desvoltare S.R.L.” will look back to the beginnings of the company´s history in 2016, when it opened its office in Bucharest. Founded to meet the needs for additional capacities of HPS Munich, HPS RO quickly developed ttowards becoming one of the most renowned full-service spacetech-companies from ESA-member states in the Eastern Europe.
Just one question to managing director Astrid Draguleanu:

From the very beginnings and through the years, you have been in the position to significantly participate in shaping and guiding the company´s development. From your perspective, which factors are the ones that keep pushing HPS forward on the road of success?
From our point of view, there are three rock solid pillars the company´s success rests on.
Number one: COMPETENCE. HPS RO is an engineering company, with driven top engineers trained in the sectors of engineering, development, assembly, secondary and tertiary structures, thermal and RF-components, mechanical ground support equipments. In addition, we have managed to combine forces with commercial and institutional suppliers and partners, contributing competencies in special segments like precision manufacturing, welding, process verification, and assembly tests. So when one´s looking for a onestop source of competence in Romania and ESA´s Eastern European presence as a whole, they will sure find it in Bucharest.

Number two: QUALITY. In the Space Industry, quality is attributed to those who manage to comply to the specific standards and building up an immaculate heritage of successful steps on the ladder to the top. HPS RO proved that it has taken those steps, and done it with at an amazing pace: In the past eight years we have contributed to a total of twelve Space Missions so far. To get an idea of what´s behind that, let us just take a more detailed look at the contributions we´ve made in the area of mechanical ground handling and support equipment, MGSE:

• Purge Equipment for the JUICE Spacecraft on behalf of Airbus Germany
• Satellite Vertical Integration Stand for the Biomass-Mission, Airbus U.K.
• Instrument & Optical Bench Lfting Frames, Copernicus Chime Mission, OHB
• Instrument Turntable Support Stand and Instrument Turntable, Instrument Alignment Trolley, Instrument Lifting Device, Multipurpose Adapter, Vibration Test Adapter, Vertical Integration Stand, Instrument Support Structure and Instrument Mass Dummy for the METOP mission, Airbus Germany
• Satellite Hoisting Device, transport containers, various adaptors – in total 14 MGSE-assemblies for Copernicus CIMR by HPS Germany.

Number three: CAPACITY. From the very beginning, it has been absolutely clear to all of us that HPS RO has a great future, by focusing on its character as a company with high professional level and not afraid of hard work. That is why building and keeping up capacities is yet another pillar we use. Take, for example, the fact that, before having even one contract to justify the expenditures, we started out from the beginning with production facilities, giving room the even the most ambitious dreams of development. And it proved to be the golden path to go: Apart from servicing all current needs of customers, we were most happy to have the capacities for starting out the series production of the HPS Satellite Dragsail product family “ADEO”, when the winds of change reached politics and deorbit technology became a legal prerequisite to let a satellite go into space to begin with. Of course, we apply this philosophy of “growth follows capacity” also to our HR-management. Today we employ a total of 20 engineers in Bucharest, growing in numbers at top speed. We are convinced that the reason for the whole success story is the delicate balance we have learned to keep in our magical triangle of COMPETENCE, QUALITY, and CAPACITY.”

The Munich-based space-tech company HPS had this development in mind more than ten years ago, when no one else was really thinking about ways to avoid space debris. With great support from the space agencies ESA and DLR, the DLR institutes in Bremen and Braunschweig, the companies DSI, Bremen, and formerly HTS, Coswig, plus a seven-digit-investment of HPS, the company´s highly committed young team of experts has created an entire product family under the generic name ADEO, from the smallest versions ADEO-P (Pico), ADEO-C (Cube) and ADEO-N(Nano), ADEO-M (Medium) and the latest member of the group, ADEO-L (Large). The development master plan not only extends even further to possible ADEO variants with up to 100 square meters of braking surface, but also leaves enough room for derivatives with completely different applications, such as the monitoring of space debris smaller than1 cm directly in space.

In its largest flight-ready version to date, L1, ADEO has a take-off weight of 10 kg at dimensions of 43 cm x 43 cm x 25 cm; in contrast to the smaller versions, this unit also requires its own power supply for motor-controlled deployment of the masts and sails. ADEO-L1 generally fits perfectly on satellites up to the 1,500 kilo class.

In the first quarter of next year, ADEO-L1 will be integrated onto a satellite of the Belgian company Redwire for its first test flight at the end of 2024/beginning of 2025 as part of a EU program, while the versions ADEO-N1 and ADEO-N2 have already passed their baptism of fire in space. Approaching the fiery finale is currently ADEO-N2, deployed in December 2022. Since then, it has already lowered its satellite from an orbital altitude of 510 km to 460 kilometers in only 12 months without the aid of any fuel or attitude control. Expected “arrival” in a completely burnt-up state: mid2025 – and thus even around five times faster than without sails and twice as fast as prescribed.

ADEO-L1 will master this path of final in-orbit verification just as safely, company boss Dr.-Ing. Ernst K. Pfeiffer is certain. As with the other versions, it will then go straight into series production for which the company has special production facilities at its Munich and Bucharest sites.

ADEO L1 “ready for lift-off”: World’s largest operational brake sail for the disposal of space debris successfully tested

HPS completes the ADEO sail fleet with its first largest version under the version named L1. Its 25 square meters of sail area unfolded successfully deployed on Monday, 4th of December 2023 in a final ground test after a complete completed PFM qualification campaign. This included vibration tests in all axes as well as tests under thermal vacuum, including hot and cold firing tests (tests to verify the deployment release mechanisms under extreme temperatures). The tests were carried out under responsibility of HPS Munich at the facilities of the DLR Institute of Space Systems in Bremen – a prime example of cooperation between industry and research & development. This final and most important test enjoyed great interest from the media (including SAT1, RTL, NTV, DPA) covering the 20-minute deflation process and interviewing the enthusiastic project team of HPS and DLR. Links to the articles and television videos can be found HERE.

This test is also a success of ESA’s GSTP program, which significantly supported the development of ADEO-L1 financially and technically. Technology programs in general are essential for independent SMEs in the space industry and their products on the way to market readiness and worldwide series sales.

The ADEO brake sails deploy after the end of the satellite’s mission and brace themselves against the resistance of the atmosphere that still prevails in orbits up to an altitude of just under one thousand kilometers. This deployment immediately leads to a drastic reduction of the speed of the satellite and the entire package sets off on its accelerated descent towards the earth’s atmosphere, where it then burns up in the frictional heat of up to two thousand degrees Celsius. The entire return process takes even significantly less time than the latest guidelines prescribe. Until recently, the process could take up to twenty-five years, while it must now be completed within five years. And, to ensure that operators follow the rules, launch service providers such as SpaceX no longer even take satellites into space if they are not equipped with the appropriate return technology from the outset.

The Munich-based space-tech company HPS had this development in mind more than ten years ago, when no one else was really thinking about ways to avoid space debris. With great support from the space agencies ESA and DLR, the DLR institutes in Bremen and Braunschweig, the companies DSI, Bremen, and formerly HTS, Coswig, plus a seven-digit-investment of HPS, the company´s highly committed young team of experts has created an entire product family under the generic name ADEO, from the smallest versions ADEO-P (Pico), ADEO-C (Cube) and ADEO-N(Nano), ADEO-M (Medium) and the latest member of the group, ADEO-L (Large).

ADEO-L1 generally fits perfectly on satellites up to the 1,500 kilo class.

Space sails from the ADEO series enable legal launch and disposal of satellites

As part of the National Program for Space and Innovation and based on the decision of the Budget Committee in November 2022, the German Space Agency launched a competition for promising space innovations. The winner can expect a fully organized and financed demonstration flight with launch by 31.12.2025. On Thursday, 23 November 2023, the Federal Government’s Space Coordinator, Dr Anna Christmann, selected Munich-based space technology company HPS as the winner of the competition in the small satellite payload category with its ADEO-Cube space sail version at the 2023 Small Satellite Conference. The ADEO product family is designed as a series with different model types (Pico, Cube, Nano, Medium, Large), with which all satellites from the Cubesats to the larger representatives with 1.5 tons (class “M”) are automatically removed from low Earth orbit (LEO) and disposed of at the end of the mission. This so-called “deorbiting” with the ADEO braking sail not only fulfills, but even undercuts the maximum duration of 5 years that will apply from October 2024 instead of the 25-year guideline that has been in place since the 1960s. Quite simply, this means that no satellite will soon be accepted for launch without special on-board technology, such as the appropriate space sail from HPS’s ADEO series, if it cannot otherwise be legally disposed of. Since SpaceX, for example, as the leading launch service provider, will be introducing this rule from October 2024, it will apply to practically all future satellites, including those that are already in the design and manufacturing phase today.
As HPS CEO Ernst K.Pfeiffer, there is still only one alternative to ADEO, but it “is chemical, expensive and – in the case of a damaged satellite – inoperable”, the passionate aerospace engineer states about the market position of the ADEO space sail: “ADEO is currently the cheapest, most reliable and cleanest solution for legal deorbiting on the global market, available in all classes thanks to series production at HPS Bucharest and HPS Munich, and highly competitive in the hotly contested commercial market for satellite technology.We at HPS, especially our development team, are all very pleased that our sustainable technology has been recognized by the Small Satellite Competition at the highest level.”

Three months from Kick-off until the breadboard of the feed is tested

The picture shows our breadboard model of the feed developed by HPS for the BANT antenna during the RF test done at MVG Italy using the StarLab measurement system. The purpose of the test is to validate the feed design by comparing the RF simulations with the results of the measurement.
Adopting the New Space approach, it took only three months from the project Kick-off until the breadboard of the feed is tested. The flight model of the BANT antenna, where this feed will be installed, will be ready to be integrated on the spacecraft at the end of this year, the satellite will be then placed in Low Earth Orbit for a remote sensing mission.

State-of-the-art antenna to serve one of the most ambitious science missions ever

HPS, leading provider of advanced antenna- and reflector-technologies, applauds the ESA – European Space Agency and to the mission prime ThalesAleniaSpace (Italy) to the launch of space mission EUCLID (within European Space Agency’s Cosmic Vision Programme) on Saturday, 01.07.2023, which aims to unravel the mysteries of the dark universe and gain insights into the nature of „dark matter“ and „dark energy“. On Sunday, 09.07.2023 it has been confirmed that the „K-band signal has been received from EUCLID“ by the ground station on Earth.

Euclid is now the biggest transmitter of data (in terms of data rate of about 74 Mbps) from trans-lunar space: Read here the article from ESA

EUCLID´s “Antenna Reflector Assembly (ARA)” developed by HPS, together with its subcontractor Invent represents a significant advancement in space communication technology. Its innovative design and advanced features make it an ideal choice for the mission, enabling high-speed data transmission and reception from the spacecraft to Earth and back, bridging the distance of 1,5 Mio km. A deep “Thank You” for the trust into our team to our Customer Chain TAS (SP) – TAS (IT) – ESA, backed by our German Space Agency DLR.

Key features of the HPS ARA:

1. Enhanced Signal Reception: The CFRP-based reflector’s high-gain capabilities, also under high temperature grades far away in L2-orbit, ensure optimal reception of the weak signals from the EUCLID spacecraft, enabling precise data collection on Earth from distant corners of the universe.
2. High-Speed Data Transmission: Equipped with the reflector‘s state-of-the-art transmission CFRP material technology, the HPS-antenna facilitates rapid data transfer in K-band, allowing for real-time analysis and quick response to mission requirements.
3. Robustness and Reliability: Designed to withstand the harsh conditions during launch and in space, the reflector assembly is built with durable materials.
4. Compact and Lightweight: HPS` antenna design prioritizes accommodation efficiency without compromising its performance. Its compact size and lightweight construction optimize interface loads to the spacecraft and payload capacity.

“We are thrilled to contribute significantly to the EUCLID mission with our advanced reflector assembly,” says Ernst K. Pfeiffer, CEO of HPS. “Our cutting-edge CFRP-technology, developed for more than 15 years, can now play a crucial role in facilitating seamless communication between the spacecraft and ground stations, allowing the investigation of dark material by huge amount of data downloaded to Earth.”

Germany´s leading collision avoidance system reliably predicts the perfect slot for descent through tons of debris and space traffic.

When, after two, five or more years of operation, a satellite is supposed to leave its orbit and re-enter Earth, it’s a ride on the skyway to hell in two respects: first, for the satellite which is destined to burn up in the atmosphere, but also for other satellites as well as for an encounter with scrap parts that could hit it like unguided missiles – and produce even more junk. Satellites equipped with the ADEO braking sail from HPS are already in automatic descent mode. From now on, however, this can be upgraded by the Collision Avoidance system from industry-leading German startup OKAPI:Orbits. The company emerged as a spinoff from Braunschweig University of Technology in 2018 after over 40 years of intensive research. This Collision Avoidance System minimizes the collision risk during the de-orbit trajectory by figuring out the situation even ten days in advance. Appropriate maneuvers are also recommended for the satellite’s control system. This is made possible by the unique AI behind OKAPI:Orbits.

“Picture a distant view of 6.72 million kilometers of orbits on which about 10,000 satellites, 1,000,000 large and medium objects and 130,000,000 small ones exist that are not currently trackable. This is how complex computing operations is. Now, we should also take into account their velocity of 20,000 to 30,000 kilometers per hour. To any human sensibility, this is pure chaos, which the artificial intelligence behind our Collision Avoidance Software handles with aplomb,” says OKAPI’s company CEO Kristina Nikolaus.

Ernst K. Pfeiffer, CEO of HPS, a medium-sized innovation company, adds, “Our ADEO braking system not only performs the fastest possible passive descent even under adverse conditions – for example, when the satellite is already dead – it is also the deorbit solution with the largest safety reserve directly on board. Customers who don’t want to rely solely on their own software to control their satellites will find a unique safety architecture for the deorbit of almost all satellites with ADEO’s optional assistance systems for position tracking (Aviosonic) and optimal descent prediction (OKAPI:Orbits) at HPS.” ADEO is under discussion as a deorbit subsystem for the satellites of Europe’s coming constellation IRIS2 and “together with the features of Aviosonic and OKAPI:Orbits it levers the constellation to the most secure and sustainable one also after satellites’ nominal lifetime.”

During descent, the combination of all three technologies onboard the satellites will increase significantly the orbit determination and prediction, which is a unique advantage also for other satellites, constellations and stakeholders like owners, operators, and insurers.

HPS is Prepared to Provide ADEO Special Stealth Sail Edition for Europe´s IRIS² Constellation Satellites

The ever-growing number of satellites orbiting Earth presents a significant challenge in terms of space debris management. As space agencies and private companies deploy increasing numbers of satellites, finding effective and sustainable solutions for their safe disposal has become paramount. In this regard, the ADEO Deorbit Sail, developed by HPS offers a groundbreaking technology that enables controlled and efficient satellite deorbiting for mitigating space debris and ensuring long-term sustainability in space. By harnessing the natural forces present in space, such as solar radiation pressure and atmospheric drag, the sail facilitates controlled reentry of satellites into Earth’s atmosphere at the end of their operational life.

ADEO has already reached ESA´s hightest level of maturity, TRL 9 and proven its reliability on a number of spaceflights; getting ready to serve Europe´s new constellation IRIS2 its NewSpace-team at HPS, Munich, take it even one step further and introduce the ADEO special “stealth” sail edition. While irritating reflections and view blocking effects of conventional constellations like Starlink cause a permanent nuisance to other users of space like astronomers during flight and deorbit, the constructors of Europe´s constellation IRIS2 are going can count on to receive from HPS an exclusive offer for a special version: the ADEO Stealth Sail –invisible, fully transparent and also available for most satellite types and operational orbits.

As HPS-CEO Ernst K. Pfeiffer explains: “Our ADEO deorbit system already presents numerous benefits and applications in satellite end-of-life management like cost- & mass-effective and sustainable deorbiting, compliance with current and future Space Debris Mitigation Guidelines, flexibility and adaptability. Now, with the special stealth version for dedicated to the architects of Europe´s IRIS2 constellation we take the decisive step to let Europe set yet another standard in space sustainability”.
