Product Description:
Ø The antenna array consists of 4 BDS B1, GPS L1, GLONASS L1 anti-jam units.
Ø The amplifier circuit has high out-of-band rejection and high linearity, ensuring that it can still work normally in the presence of strong jamming signals.
Ø Built-in voltage regulator circuit, can work normally in a wide input voltage range.
Main Function:
1. Receive satellite signals from GPS-L1, BDS-B1, Glonass-L1, and Galileo-E1.
2. It can reject various types of broadband and narrowband jamming such as harmonics, frequency sweeps, pulses, white noise, frequency modulation, amplitude modulation, and phase modulation for the GPS-L1, BDS-B1, and Glonass-L1 frequency bands.
1. It has the functions of working parameter configuration, query and retention.
2. Equipped with software online upgrade function.
