EN-150 Inertial Measurement/Navigation Unit
High accuracy FOG-based IMU for UAVs, Dismounted Soldiers and Platform Stabilization
The EN-150 Precision Fiber Optic Inertial Measurement/Navigation Unit is our smallest Fiber Optic Gyro-based Inertial Measurement Unit (IMU) and the smallest closed-loop FOG IMU available today. This high-accuracy unit is designed to operate as both an inertial measurement unit or navigator with up to two-times the performance of competing IMUs.
It is ideal for use as an inertial navigation system for UAVs, dismounted soldier, gun stabilization/targeting applications as well as navigation in GPS-denied environments. The EN-150 is a higher accuracy inertial system that is one-third the volume and weight of a legacy RLG-based IMU product with better performance.
The system incorporates three precision FOGs and three precision MEMS accelerometers, as well as integrated optics and next-generation FPGA electronics for high-efficiency calibration and system modeling. With the option of full navigation capability, the EN-150 includes options for coning and sculling compensation, sophisticated Kalman filtering and external aiding e.g. via GPS.
The EN-150 is available in three performance variants:
