Overview
Product Overview
1.WTRTK-960 is a new generation of BDS/GPS/GLONASS/Galileo/QZSS full-system multi-frequency high-precision RTK positioning module, based on the new generation of RF baseband and high-precision algorithm integrated GNSS SoC chip—NebulasIV designed by Unicore Starlink.
2.It can simultaneously track BDS B1I/B2I/B3I/BIC/B2a*, GPS L1C/A /L2P/L5, GLONASS L1/L2, Galileo E1/E5b/E5a, QZSS L1/L2/L5 and other signal frequencies.
3.It is used in high-precision navigation and positioning fields such as deformation monitoring, high-precision GIS, drones, lawn mowers, precision agriculture, surveying and mapping, and intelligent driving.
