TOA2200-BG dual-mode single frequency high-precision positioning and orientation system
Product details
The TOS220-BG dual-mode single frequency high-precision positioning and orientation system is a miniaturized high-precision positioning and orientation system based on the satellite navigation chip (OTrack-128) independently developed by Dongfang Lianxing, which uses multi RF unit synchronization technology. The system supports local RTK and RTD functions, is compatible with Beidou ground-based augmentation system and satellite based augmentation system, and can receive satellite signals from dual BDS (B1) and GPS (L1) antennas at the front and rear. It adopts carrier phase relative differential positioning technology to achieve high-precision and high stability heading measurement, and heading accuracy does not drift over time.
TOS220-BG is equipped with a 6-axis MEMS IMU, which can be expanded to include a 3-axis magnetic compass and barometer, enabling INS/GNSS and multi-sensor integrated navigation functions, and achieving continuous seamless high-precision positioning and orientation.
