HTS-IMU-LP2 Inertial Measurement Unit is a small, tactical grade, ten degrees of freedom inertial measurement unit based on MEMS technology, which includes a triaxis gyroscope, a triaxis accelerometer, triaxis magntometer, and pressure senor. This IMU uses flexible connection technology, built-in full temperature compensation, installation misalignment angle compensation, nonlinear compensation and other compensation algorithms, and can output stable and reliable measurement data for users after error compensation under static, dynamic and harsh conditions.
The HTS-IMU-LP2 inertial measurement unit adopts the advanced domestic MEMS components, it can effectively reduce the cost. The HTS-IMU-LP2 features with high stability, compact size and light weight. The HTS-IMU-LP2 inertial measurement unit is packaged in a module that is approximately 44 mm × 47 mm × 14 mm and includes a standard connector interface.
