This anti-interference system is designed to receive, amplify, downconvert, filter, and perform anti-interference processing on four channels of Beidou BDS B1, GPS L1, and GALILEO E1 frequency signals.
It operates from a +1.2V to +32V supply voltage and consists of four main components: an antenna array, a radio frequency (RF) assembly, an anti-interference processing unit, and a receiver.
It can counteract three broadband interference sources, providing high-precision positioning and precise timing even under strong interference conditions.
