Description
The Inertial Labs Inertial Measurement Unit (IMU-P) is an Advanced MEMS sensors based, compact, self-contained strapdown, industrial and tactical grade Inertial Measurement Systems and Digital Tilt Sensor, that measures linear accelerations, angular rates, Pitch & Roll with three-axis highgrade MEMS accelerometers and three-axis tactical grade MEMS gyroscopes. Angular rates and accelerations are determined with high accuracy for both motionless and dynamic applications. The Inertial Labs IMU-P is breakthrough, fully integrated inertial solutions that combine the latest MEMS sensors technology.
Fully calibrated, temperature compensated, mathematically aligned to an orthogonal coordinate system, IMU demonstrate less than 1 deg/hr gyroscopes and 0.005 mg accelerometers bias inrun stability with very low noise and high reliability.
Continuous Built-in Test (BIT), configurable communications protocols, electromagnetic interference (EMI) protection, and flexible input power requirements make the Inertial Labs IMU-P easy to use in a wide range of higher order integrated system applications.
The Inertial Labs IMU-P models are able to get an aiding data from external source of GNSS and then to output full spectrum of INS data (Positions, Attitude, Velocity and Time).
The Inertial Labs IMU-P was designed for applications, like:
- Antenna and Line of Sight Stabilization Systems
- Passengers trains acceleration / deceleration and jerking systems
- Motion Reference Units (MRU)
- Motion Control Sensors (MCS)
- Gimbals, EOC/IR, platforms orientation and stabilization
- GPS-Aided Inertial Navigation Systems (INS)
- Attitude and Heading Reference Systems (AHRS)
- Land vehicles navigation and motion analysis
- Buoy or Racing Boat Motion Monitoring
- UAV & AUV/ROV navigation and control
