HG1700

High Performance Tactical Grade IMU

HG1700

Proven technology for control applications

The HG1700 is a high performance tactical-grade inertial measurement unit (IMU) designed to meet the needs of a broad range of guidance and control applications. The HG1700 has been successfully deployed on a wide range of weaponry, UAVs, stabilized platforms and commercial applications. Honeywell has manufactured and delivered over 350,000 HG1700 IMUs worldwide –more than 10 times the number of its closest competitor and has unsurpassed tactical grade IMU performance and reliability.

The HG1700’s three ring laser gyroscopes (RLG), three quartz resonating beam accelerometers (RBA) and associated electronics are all environmentally sealed in rugged aluminum housing. The sensors in the HG1700 IMU have excellent stability characteristics –the bias stability term is negligible in thermally stable environments –and as such bias performance is specified as the combination of both stability and repeatability. The HG1700 also employs an external environmental ring isolator to filter unwanted sensor inputs commonly encountered in real world applications.
