The LP-RESEARCH Motion Sensor LPMS-USBAL2 is an inertial measurement unit (IMU) / attitude and heading reference system (AHRS) with rugged housing. The unit is very versatile, performing accurate, high speed orientation and relative displacement measurements. By the use of three different MEMS sensors (3-axis gyroscope, 3-axis accelerometer and 3-axis magnetometer) low-drift, real-time orientation data around all three axes is achieved. Additionally, temperature and barometric pressure sensors allow accurate altitude measurements. The LPMS-USBAL2 is connects to a host system via USB 2.0, reaching data transmission rates of up to 400Hz.
The unit contains a 32-bit digital signal processor capable of running all calculations on-board in real-time. For more information on our sensor fusion method please refer to the IMUcore description.
