The TX43 GNSS modules 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 L1 L2, GLONASS G1 G2,Galileo E1 E5b and BDS B1I B2I) 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 reception.

The TX43 supports the GNSS and their signals as shown in table

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.
