Reflektor-Antennen
Antennen sind eine der wichtigsten Subsystem-Domänen von HPS, die das Unternehmen vollständig mit dem Portfolio von Side‐Deployable-Antennas, Top Deck- und Feeder Link- Antennas über Dual Gridded-, GNSS- und Large Deployable Antennas bis hin zu Radar- und selbst Bodenantennen abdeckt.
In besonderem Fokus liegt bei Kommunikationsantennen die HPS-Spezialisierung auf Ka- und Q/V-Band. Spezielle Merkmale der Antennen-Subsysteme von HPS sind ihr geringes Gewicht, hohe Reflektivität, thermo-elastische Stabilität und hervorragend hohe Eigenfrequenz.
HPS liefert diese Antennen-Subsysteme komplett und zügig aus einer Hand – Vorteile, die in Kombination mit den erwiesenen qualitativen Merkmalen zur Beauftragung und „Flight Heritage“ des Unternehmens für die Mission „Heinrich Hertz“ des Deutschen Zentrums für Luft- und Raumfahrt (DLR), sowie für die ESA Mission EUCLID geführt haben.
