Key highlights
The ISIS GPS antenna is a part of a new generation of antennas designed for nanosatellites. It is an off the shelf active antenna. The antenna is mounted onto a Rogers PCB, ideal for high-frequency RF circuitry ensuring fewer losses than traditional FR-4 PCBS. The ISIS GPS patch antenna is a compact, low mass active antenna, designed for GPS-L1. This passive antenna is suitable for providing CubeSat platforms with precise positioning and is compatible with the ISIS structures.
