product description

the gp206t is a new generation of compact, high-precision multi-frequency receive positioning and orientation system for the uav, driving test and intelligent driving. it supports full-system multi-frequency rtk positioning and orientation and can be used as a mobile station or base station. the gp206t can simultaneously track multi-frequency points such as b ds b1/b2 gps l1/l2 glonass l1/l2 galileo e1/e5b sbas/qszz.the gp206t uses the new generation of high-performance gnss soc chips from nephis-ii, which integrates two arm processors and a dedicated dual-floating processor to perform baseband and rtk solution functions on a single chip. focusing on the use of high-precision products in complex environments such as urban blocks, shades and bridges, the new generation of ugypsophila rtk processing technology developed by rion technology makes full use of high-performance data sharing in nebulas-ii chips. the ability to fully optimize the multi-dimensional rtk matrix pipeline calculation, the rtk processing capability is enhanced by more than 80%, and the directional solution of more than 25 dual-antenna satellites and the re-capture time within 1 s can be realized.rion technology integrates on-board mems chip and u-fusion integrated navigation algorithm to effectively solve the problem of positioning result interruption caused by satellite signal loss, and further optimizes the positioning of directional output in complex environments such as buildings, tunnels and viaducts. continuity and reliability. this manual is suitable for the double beidou positioning orientation board gp206t, indicating its technical status, technical indicators and user interface.
