Function
1) Full-band protected CRPA antenna for 4-channel GPS L1/L5 signal receiving, amplifying, down-conversion, filtering and processing.
2) It adopts 12V~32V wide voltage power supply, consisting of antenna array, RF module and processing module. It can protect against abnormal electromagnetic signals in three
directions, suitable for high-precision positioning scenarios with sensitive electromagnetic environment, and greatly improves positioning stability under complex electromagnetic
conditions.
3) It supports signal types: wideband, narrowband, sweep frequency and pulse.
