Product Details

ER-MG05 Small Size And High Performance Integrated Navigation Board


The ER-GM05 Small Size And High Performance Integrated Navigation Board is a compact, high-performance integrated navigation product developed. 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.

Combining the absolute accuracy of GNSS positioning with the stability of inertial measurement, in a complex environment, even if the GNSS signal is completely blocked, ER-GM05 can still provide stable and continuous positioning and attitude calculation results.

The ER-GM05 product has functions such as moving base alignment, inertial / satellite integrated navigation, autonomous zero-speed correction, and independent calibration. It can be combined with odometer data to further improve the accuracy under car navigation.

Through the standard serial port, using a simple command and data recording interface, you can complete all settings and data collection. Once the hardware is installed, the system can be set up within minutes.

ER-GM05 is an OEM board 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 user integration and large-scale Production and other characteristics.
