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). 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.

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.”

ESA´s “Zero Debris Charter” finalized – HPS among the first to sign

Initiated by ESA´s office for “Strategy and Transformation” a considerable group of European space companies, including HPS, got together in order to jointly draft and now implement this continent´s set of rules for sustainable use of space. HPS is one of the first companies to sign the document on November 7th, 2023. Though legally non-binding, the “Zero Debris Charter” aims at putting an end to the inconsiderate and irresponsible pollution of space with tech-junk. In detail, the Charter clearly names the following targets:

1. The probability of space debris generation through collisions and break-ups should remain below 1 in 1,000 per object during the entire orbital lifetime. A suitable aggregate probability threshold for constellations of satellites in the low Earth orbit region should be identified.
2. Timely clearance of low Earth orbit and geostationary Earth orbit regions should be achieved with a probability of success of at least 99% after end of mission, including through external means when necessary.
3. The casualty risk from re-entering objects should remain significantly lower than 1 in 10,000, striving towards zero casualty. A suitable aggregate risk threshold for constellations of satellites in the low Earth orbit region should be identified.
4. Routine and transparent information sharing should be facilitated and active participation in strengthening global space traffic coordination mechanisms should be encouraged.
5. Access to timely and accurate data on space objects down to a size of 5 cm or smaller in low Earth orbit and 20 cm or smaller in geostationary Earth orbit should be improved to enhance decision making capabilities for collision avoidance.*

Ernst K. Pfeiffer, CEO of HPS at the signature ceremony: “In our days now space is rapidly developing into the most important resource for the implementation of new technologies shaping our future on Earth. All efforts to preserve space from the beginning are therefore nothing less than efforts to preserve the fundamental conditions of life and its prosperity for humankind´s generations to come.”

SpaceTech Expo Bremen: HPS presents the ADEO space deorbit-sail, the world’s only product series of its kind for the legal disposal of disused satellites

Less than 36 months ago, they were regarded by many as nothing more than political empty phrases: the “Green Deal” of the EU Commission in Brussels and the “National Orbital Debris Implementation Plan” of the White House in Washington. Satellites continued to be launched into near- and far-Earth orbits with the prospect of becoming junk and endangering other missions for a quarter of a century after they finally burned up in the atmosphere. But that’s over now: With the adoption of the “Zero Debris Charter”, ESA has committed itself on November 7, 2023 to taking steps towards total avoidance of any space debris from 2030 at the latest, and even more concretely, namely already from October 2024, SpaceX, with over one hundred launches per year the world’s most important launch service, will no longer transport any payloads that are not equipped for their disposal within a maximum of 5 years after the end of mission operations. And as early as 2023, the U.S. FCC (“Federal Communications Commission”), as the supervisory authority for the allocation of radio frequencies, sentenced a satellite operator to a fine of $150,000 for prolonging the operation of his satellite with the propellant actually reserved for disposal, thus recklessly endangering all other missions in the vicinity. While the sum might make some people smile, the FCC has now put an end to all symbolism with its decision to no longer grant radio licenses to satellites without on-board technology for return (technical term: “deorbit”) within 5 years of the end of operations. Under the double threat of operation AND launch ban, practically all operators are forced to equip new satellites only with guaranteed reliable deorbit technology from now on.

This can be done with the on-board propulsion system using chemical propellants while shortening mission and profit, but even that does not work in case of satellite failure and is also comparatively expensive due to the need for constant control monitoring from the ground.
The alternative is called ADEO: from HPS (Munich and Bukarest) a space sail, self-deploying at the end of the mission, which automatically removes the satellite from space well below the specified deorbit times, is ideally suited as baseline-tech and emergency parachute. Already 36 million flight kilometers before the planned maneuver, the German specialist for orbit guidance and collision avoidance OKAPI:Orbits (Braunschweig) as a cooperation partner calculates the point for the descent without risk for other satellites. In addition, HPS partner number two, the Italian company AVIOSONIC, in constant liaison with the worldwide air traffic control stations, ensures via new ADEO-features highly accurate position conrol and spares aircrafts from hits by any satellite parts that may not have burned up.
The ADEO product family with officially attributed highest possible level of reliability (“TRL 9”) holds tailor-made solutions for all satellites from the tiny Pico- and Cube-Sat up to the 1.5 tonner and for all low-Earth orbits up to a distance of 900 kilometers from Earth. All ADEO lines are mass-produced by HPS, yet they feature adaptive design for special requirements that may arise from satellite design.
The prices of all ADEO models without exception are considerably lower than the expenditures required for deorbiting with chemically driven engines – apart from the fact that the safety of the deorbit of even these satellites – for example in the event of a system failure – can actually only be guaranteed by an ADEO system carried along as a backup.

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.

Aviosonic´s patented DeCAS for tracking and re-entry footprint prediction extending high-tech-lead of Europe´s satellite deorbit system “ADEO” unassailably

(Munich-Milano, May 10^th, 2023). At testified TRL-9 and with solid flight heritage the sail system “ADEO” already is the leading device for quickly deorbiting almost all satellites, thus preventing spacecrafts after their end of mission from becoming as well as producing new space junk for years to come. Because it is a sail, it does not produce any pollution itself, chemical or otherwise, and because this very sail will be in its next version also transparent and absolutely non-reflective, it does not cause any irritations to any space observer on earth. Munich based spacetech innovator HPS, a medium sized company with a subsidiary in Romania and a total headcount of 80, has invested – together with several institutional and industrial partners – 12 years of constant development and qualifying into ADEO, and is now ready to take yet another giant leap by joining innovative forces with Aviosonic Space Tech, Milan/Italy.

Aviosonic Space Tech, born in 2015, owns the patented DeCAS system (Debris Collision Alert System) for in-orbit/de-orbit tracking and re-entry footprint prediction of space vehicles. DeCAS is a 1U mm system which always maintains a constant link with the ground operation center allowing precise information on the satellite position, aliong with the calculation of the re-entry footprint in real time, with the aim of collision avoidance between satellites, satellites and aircrafts as well as to alert government agencies. The technical characteristics and modularity allow DeCAS to be installed on any space vehicle, offering different services depending on the mission requirements. DeCAS, which took part in different space missions, provides a unique service for satellite tracking, decommissioning and re-entry prediction in real-time.

Prof. Piermarco Martegani, CEO of Aviosonic Space Tech says:”The integration between DeCAS and ADEO allows the creation of a unique product on the market capable of strongly implementing the safety of space operations both during orbital and decommissioning re-entry phses, even in the event of failure of the hosting satellite. This safety information is also needed by the Air Traffic Management System. The collaboration between Aviosonic Space Tech and HPS is the demonstration that in order to guarantee safety during space operations, an international cooperation between SMEs is necessary.”

HPS-CEO Ernst K. Pfeiffer shows bulletproof confidence in the future of ADEO on the world market and emphasizes: “ADEO has all the facts on its side: first, all space industry badly needs a deorbit device like ADEO, since the faster the sail opens free orbit positions, the longer we can keep space as a sustainable surrounding. And, from second to infinite: ADEO combines TRL9 and flight heritage, offers a comprehensive range of models, beats economically as well as ecologically any other type of deorbit device, also it is already in serial production at HPS. And now we even join forces with the two outstanding innovators in their fields, and others will join, underlining once again what´s at the core of ADEO: 100 percent European, 100 percent SME, 100 percent sustainability in space – and exactly what Europe wants for Iris².”

All Launch Windows are closing for Satellites Without ADEO or Equivalent Deorbit Tech

After FCC, SpaceX, and ESA now also the three German startups racing for the smaller launchers` pole position in the commercial market made it clear that tickets to space will be available only to satellites prepared to be able to deorbit quickly after service.

The companies made their points recently in statements to the German space magazine “Raumfahrt Concret”.

For more details see: RCI-Newsletter-1-2023.pdf (hps-gmbh.com)

Ernst K. Pfeiffer, CEO of HPS, the German spacetech company that has developed ADEO to become the number 1 deorbit device for spacecrafts on the market, comments: “While we witness many cases of exorbitant differences in opinions when it comes to principles the space industry should follow, it is with great relief that we see this case ruled by unanimous voices echoing the new green spirit of deorbit from everywhere.”

3 – 2 – 1 – Next liftoff for the HPS space sail ADEO-N3 on the satellite carrier ION of the Italian mission provider D-ORBIT

Already in the heat of last summer, HPS in Munich was preparing for the third mission of the innovative space brake sail ADEO-N, which unfolds automatically at the end of the mission and drives “its” satellite into the atmosphere to burn up. This technology avoids the formation of new space debris already on the ground and finally makes space missions sustainable.

The ION Satellite Carrier with ADEO-N3 with its sail area of 5sqm has been on board a Falcon 9 since the picture book start on January, 31, 2023 from spaceport Vandenberg, California, now on the way to the target orbit at 270 to 500 km altitude at 53 degrees inclination. Probably by the end of 2023 ADEO-N3 will then, as on previous flights – including one with ION also on Falcon 9 – deploy the braking parachute and remove its ION Satellite Carrier from orbit without leaving any residue many times faster than usual. With the flight heritage accumulated by then, the mature ADEO system heralds a “green” space age. Because at least for European missions or missions from Europe, there will – in all probability – no longer be any more launches without deorbit tech on board: The Green Deal of the EU will then also apply to “clean-green missions” in space.

On the current flight, ADEO-N3 acts as another verification of maturity for HPS. D-Orbit and HPS already captured what will happen high above the earth during a nominal mission as historical testimony on video during the last flight:

The attached video, recorded directly on site with the on-board camera of the ION satellite of the Italian cooperation partner D-Orbit, provides live proof: with the product of HPS, which is now ready for series production after twelve years of development with great support from ESA, DLR and the Bavarian government, a new era of responsibility in space is beginning. ADEO is manufactured in series by HPS at its sites in Munich and Bucharest, primarily for constellation satellites. ADEO products are available for satellites weighing up to 2,500 kilograms at flight altitudes of up to 800 km. Even higher-flying satellites can be operated with ADEO if they have previously lowered their orbit accordingly using their own propulsion. HPS CEO Ernst K. Pfeiffer: “With ADEO on board, satellites do not become space junk in the first place. And at conditions that are ALWAYS more economical than all other options.”

Historical video evidence
from HPS and D-Orbit

On December 15, 2022, at 12:10 UTC, the world’s unique ADEO braking sail from the German space technology company HPS GmbH, Munich, opened the chapter of sustainability for international spaceflight 500 kilometers above the Earth: as planned, on time and precisely, the sail attached to the ION SCV 003 satellite unfurled over an area of 3.6 square meters to remove “its” satellite from orbit in the shortest possible time without leaving any residue, thus avoiding hazards for other space vehicles and making room for the next generation of satellites at its former orbital position. Preliminary studies and calculations indicate that this will reduce the descent time not by half, as originally expected, but rather by as much as five times.

The attached video, recorded directly on site with the on-board camera of the ION satellite of the Italian cooperation partner D-Orbit, provides live proof: with the product of HPS, which is now ready for series production after twelve years of development with great support from ESA, DLR and the Bavarian government, a new era of responsibility in space is beginning.

Qualification success for HPS in space: Smallest version of ADEO braking sail successfully deployed

For 16 months now, an ION satellite carrier of the Italian service provider for unmanned space transportation D-Orbit has been orbiting the Earth in low orbit. Launched by a Falcon 9 on June 30th 2021, it has only one last task after the mission launch of the high-tech passengers from eleven countries: to sail gently as if on “angel wings” to the edge of the Earth’s atmosphere in the shortest possible time with the help of the autonomous braking sail ADEO from the Munich-based space company HPS and to burn up there without leaving any residue.

The test model is the smallest variant of the ADEO product family with a weight of 800 grams, a packing size of 10x10x10 cm and an unfolded sail area of 3.6 square meters. This ADEO-mission “Show me your Wings” is now the final proof-of-concept in a series that also included a first flight with Rocket Lab’s Electron in 2018 and several parabolic flights from 2019 to 2022.

After the end of this nominal ION mission called “Wild Ride”, ADEO’s decelerator sail now deployed in front of the “eyes” of the integrated camera and immediately initiated descent (“deorbit”). ADEO completes deorbiting many years faster than the “unbraked” satellites currently still in widespread use and clears its operational position in orbit correspondingly earlier for a new satellite, which also prevents uncontrolled pollution of space by collision debris. In addition, ADEO helps extend the satellite’s uptime by allowing the sail to continue its descent even when the satellite is out of power and propulsion.

Incidentally, the time required for deorbiting is accurately measured so that it can be used for any necessary recalibration of the HPS deorbit timer. This is a globally unique computational program for predicting the deorbit times of all possible satellites with and without ADEO braking sails. The theoretically developed mathematical algorithms of the computer are thereby differentially refined by empirically obtained data from the field. The ADEO Deorbit Timer is a valuable service to HPS customers around the world.

Series production of the ADEO versions for all satellite classes with flight altitudes below 900 kilometers is in full swing at HPS in Munich (Germany) and Bucharest (Romania). The first companies, such as NewSpace startup Reflex Aerospace (Berlin and Munich), have already signed letters of intent to equip their entire future satellite fleet with ADEO or have announced that they will do so shortly. Others like BST, Berlin, are integrating ADEO as a standard option in their offerings to customers. An additional surge in demand was triggered in the fall of 2022 by the announcement by international policymakers that satellite deorbit times would be drastically shortened down to just 5 years due to the extreme increase in usage density on all orbits, and that corresponding additional equipment would be required by law.

The extremely sharp picture proof of the successful unfolding now opens a new chapter in the history of HPS, in addition HPS CEO Ernst K. Pfeiffer: “And again, a new chapter of programmatic success could be written, which is only possible through trusted space partnerships: research and development with institutes (like the Fraunhofer Institute in Freiburg and the DLR in Bremen) in the early and development stages, financial support from the Bavarian State and the German Space Agency, a vey strong engagement of  ESA within its GSTP-program (without this support, including the people behind it, we would still be a long way off!!!), the extremely dedicated staff of my NewSpace team and finally with the people of the system companies, like D-Orbit, who finally, made possible to download from space the image of the unfolded sail, which is important for our next chapter. A great step for HPS, another step for sustainable spaceflight.”
