SAJ GNSS Shield
SAJ is a passive shield installed around an existing conventional or CRPA GNSS antenna to attenuate jammer and multipath signals. It covers L1 and L2 frequencies and provides 20 to 30 dB of unwanted-signal suppression, including interference arriving at theta angles of 90 degrees and above.
Each shield is mechanically adapted to the host antenna and platform, allowing the protective element to be added to existing GNSS installations. The proven capability has been installed and tested on multiple platforms, supplied to domestic and international drone manufacturers and military institutions, and deployed in military field operations.
