About
The ISISPACE GNSS Active Patch Antenna combines compact design, low mass, and flight-proven reliability. Perfectly engineered for GPS-L1 (1575 MHz) 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. It features integrated SAW filters and an LNA for active amplification, providing a total signal gain of 34.5 dB. The antenna is qualified for up to 15g quasi-static acceleration in all axes, making it suitable for launch environments.
A single MMCX connector is used for both power supply and RF output, simplifying satellite integration. Flight heritage since initial CubeSat deployments.
