The GNSS Anti-Jam Antenna from ST Engineering is a Controlled Reception Pattern Antenna (CRPA) that operates at 1575.42 MHz (GPS L1 C/A & L1C, BeiDou B1C) and 1561.098 MHz (BeiDou B1I). It uses a 4-element antenna array with a 20 MHz bandwidth and integrates adaptive digital nulling for anti-jam operation in multi-interference environments. This 50-ohm antenna provides interference suppression of up to 40 dB, supports up to 3 simultaneous nulls, and has a noise figure of 5 dB. It is designed to mitigate CW, chirp, and AWGN interference.
The GNSS Anti-Jam Antenna a DC supply of 24 to 28 V and has a power consumption of less than 12 W. It is available in a compact enclosure measuring 188 × 48 mm and operates over a temperature range from -40°C to +70°C. This anti-jam antenna is ideal for use in intelligent traffic management, vessel safety, ship navigation, fleet management, and autonomous platform applications.
