Overview

The anti-interference system is used to receive 4 channels of Beidou BDS B1, GPS L1, and GALILEO E1 frequency signals, and perform amplification, down-conversion, filtering, and anti-interference processing.
The system uses a +5 V power supply voltage and consists of four main components: antenna array, RF component, anti-interference processing component, and receiver.
The system can counter three broadband interference sources and provide high-precision positioning and precise timing under strong interference conditions.
