Honeywell HG1700 Inertial Measurement Unit
Proven technology for a wide range of guidance and control applications. Possibilities of Navigation. Made Easy.
Proven – Dependable – Accurate
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 offers unsurpassed tactical-grade IMU performance and reliability.
Description
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.
The HG1700 consumes less power than competing fiber optic gyro-based systems and simplifies system integration by offering many configurable features, such as data rate output and flight control filtering. External heat sinks and cooling are not required by the HG1700, facilitating greater flexibility in systems design and integration.
Configurations
The HG1700 is now offered in two variants, four performance grades, and thirty different off-the-shelf configurations, more than any other IMU in its class. The HG1700SG is the latest fully qualified variant and has the same best-in-class capabilities as the HG1700AG but in a smaller package. The HG1700SG is shorter and lighter than the HG1700AG.

¹ The specified gyro and accelerometer bias includes both repeatability and stability terms. The stability term is negligible for temperature stable environments. The Allan Variance measurements are dominated by Random Walk terms.
Export Control Classification Number (ECCN) is 7A003.d.1.
