The LP-RESEARCH Motion Sensor LPMS-IG1 is an inertial measurement unit (IMU) / attitude and heading reference system (AHRS) in an IP67-rated enclosure (waterproof).
The unit is very versatile, performing accurate, high-speed orientation measurements. The 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.
LPMS-IG1 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.
