Overview
Product Overview
1.WTRTK-982 module is the general name of the high-performance BDS/GNSS full-constellation high-precision positioning and orientation module series with a size of 26X38MM.
2.The module is all based on the new generation of RF baseband and high-precision algorithm integrated GNSS SoC chip-NebulasIV designed by Unicore Starlink.
3.The main antenna and the slave antenna simultaneously track the full system frequency points including the Beidou III global signal to achieve on-chip RTK positioning and dual-antenna directional solution.
4.It has DuaI-RTK dual RTK engine technology and differential input RTCM format adaptive recognition function.
5.The built-in advanced anti-interference unit ensures that the module can provide reliable and accurate positioning accuracy even in complex electromagnetic environments.
For high-precision navigation and positioning fields such as drones, autonomous machines, precision agriculture and intelligent driving
