LPMS-IG1P: 9-Axis Inertial Measurement Unit (IMU) / AHRS and GPS Receiver with USB / CAN / RS232 Connectivity

9-axis IMU with GPS receiver


The LP-RESEARCH Motion Sensor LPMS-IG1P is a 9-Axis inertial measurement unit (IMU) / AHRS and GPS receiver with USB / CAN / RS232 connectivity in an IP67-rated enclosure (waterproof).

This unit is very versatile, performing accurate, high-speed orientation measurements. Output of three separate low-noise single-axis gyroscopes is fused with three-axis accelerometer and magnetometer data to achieve low-drift, low-latency 3D orientation information.

As the low-noise gyroscopes only support angular rates up to 400dps, we integrated an additional gyroscope for rates up to 2000dps with the device. Users can select which gyroscope they would like to use as orientation data source.

For more information on our sensor fusion method please refer to the IMUcore description. Wer offer customized algorithms for using LPMS-IG1P as dead reckoning sensor for AGV and automotive applications using a fusion of IMU, GPS and vehicle odomotery data.

LPMS-IG1P connects to a host via USB communication or using optionally either a CAN bus or RS232 connection. Please specify your preference when ordering this component.

All sensor parameters and data transmission options can be controlled by our IG1-Control software. For direct interfacing to Windows / Linux PC or embedded system we provide extensive library support.
