The anti-jam system is designed to receive, amplify, down- convert, filter, and perform anti-jam processing on 4 channels of BeiDou BDS B1 and GPS L1 ，GALILEO E1 frequency signals.
It operates on a +5V supply voltage and consists of four main components: antenna array, RF components, anti-jam processing components, and receiver.
It is capable of countering three broadband interference sources, providing high-precision positioning and precise timing under strong interference conditions.
4 channels: BDS B1 and GPS L1 antenna arrays
（ Other frequency bands can be customized, such as GPS L2/L5, etc. ）
E1 :1 575.42MHz ± 1 .023MHz
combined interferences such as broadband, sweep frequency and pulse;
sources from different directions
