ER-GB-05 Small Size And High Performance Integrated Navigation Board
ER-GB-05 small high-performance integrated navigation board is a compact, high-performance integrated navigation product. Based on the mature multi-mode and multi-frequency, dual-antenna positioning and orientation, high-precision GNSS board and integrated MEMS inertial measurement unit, it can provide low-latency, high-precision 3D position, velocity, and attitude, as well as IMU raw acceleration and angular velocity measurement results.
In the view of the absolute accuracy of GNSS positioning and the stability of inertial measurement, even if the signal is completely blocked in a complex environment, ER-GB-05 can still provide stable and continuous positioning posture calculation results.
ER-GB-05 has many functions, such as moving base alignment, inertial/satellite integrated navigation, autonomous zero-speed correction, and independent calibration that can be combined with odometer data to further improve the accuracy under car navigation.
Through the standard serial port, all settings and data collection can be completed using a simple command and data logging interface (after the hardware is installed, the system can be set up within a few minutes).
ER-GB-05 is an OEM board that specially launched for applications such as autonomous driving, mobile measurement, drones and various attitude stabilization platforms. It has a small size, light weight, low power consumption, low cost, easy for integration and other characteristics.
