About
By placing the low-noise amplifier directly within the antenna housing, the GNSS signal is amplified before it travels through any cable to the receiver. This mitigates the noise contribution of cable losses at the most critical point of the RF chain — the first stage — where every tenth of a dB of additional noise figure directly degrades receiver sensitivity. The LNA delivers a typical gain of 22 dB and a noise figure of 1.8 dB, ensuring the GNSS receiver operates with the cleanest possible input signal. The LNA Board integrates a sharp S-Band filter that provides strong rejection of signals from onboard S-Band TT&C antennas, which operate adjacent to the GNSS band. This eliminates the need for an external filter in the RF chain and significantly reduces the risk of intermodulation or desensitisation of the GNSS receiver caused by S-Band transmissions during TT&C uplink. The antenna and LNA block are co-qualified as a single assembly for LEO missions up to 7 years in orbit plus 1 year on ground. The GNSS antenna element is protected by a PEEK radome with anti-ESD coating. The LNA electronics are radiation-hardened by design: the DC/DC parts are TID tolerant up to 40 krad, and the GaAs RF section is intrinsically tolerant up to 300 krad — covering the full radiation dose expected in most LEO missions.
