ISISPACE GNSS Patch Antenna combines compact design, low mass, and flight-proven reliability. Perfectly engineered for GPS-L1 and GALILEO-E1, it ensures pinpoint positioning and integrates seamlessly with ISISPACE structures. The antenna is mounted onto a Rogers PCB, ideal for high-frequency RF circuitry, ensuring lower losses than traditional FR-4 PCBs. As part of a new generation of CubeSat antennas, it offers unmatched performance right off the shelf.
