High Precision RTK and Heading Module
All-constellation Multi-frequency
TOP682 is the all-constellation multi-frequency high precision RTK and heading module, developed by TOPGNSS
The module istargeting Roberts, UAVs and intelligent drive applications.TheTOP682 can provide reliable centimeter-level accuracy and high accuracy heading output at high update rate.
(432 channel tracking) small size(60x60*6.0mm).
It can simultaneously track GPS L1/L2 + BDS B1I/B2I + GLONASSL1/L2+Galileo E1/E5b+QZSS.
The TOP682 adopts UNICORECOMM’s new-generation “UGypsophila” RTK processing technology and takes advantage of the high-performance data sharing capability and super-simplified operating system within the NebulasII GNSS SoC chip. It performs sufficient optimization on the multi-dimensional RTK matrix pipeline computation, resulting in much higher RTK processing capability. With on-board MEMS chip and UFusion integrated navigation algorithm, TOP682 can maintain excellent application experience even in the most challenging environments such as urban canyons,tunnels and obstructions.
