UD-R8003GM is the high precision integrated navigation system; based on the latest generation of 22 nm process vehicle grade GNSS SoC chip, with a high-precision IMU that has been treated with full temperature secondary calibration, so improve key indicators such as zero bias instability. SAIF (Smart Advanced Interference Defense) high-performance composite interference suppression technology is adapted. UD-R8003GM has obvious advantages in dynamic performance, and can effectively cope with harsh environments such as satellite signal interference and loss.
