The TX43 are concurrent GNSS receivers that can receive and track multiple GNSS systems. Owing to the multi band RF front-end architecture, all four major GNSS constellations (GPS, GLONASS Galileo and BDS) can be received concurrently. All satellites in view can be processed to provide an RTK navigation solution when used with correction data. The TX43 receiver can be configured for concurrent GPS, GLONASS, Galileo and BDS plus QZSS,SBAS reception to provide a high performance position reporting and navigation solution. Based on the high performance TX43 position engine, these receivers provide exceptional sensitivity and acquisition times and interference suppression measures enable reliable positioning even in difficult signal conditions.
