HG2802

Fiber Optic Gyro Inertial Measurement Unit

HG2802

Smallest SWAP-C IMU on the market

The HG2802 is a higher operating range option within the HG2800 family of high-performance tactical grade IMUs that includes Honeywell’s next-generation micro-electro mechanical systems (MEMS) accelerometers in addition to closed-loop fiber optic gyros (FOGs), providing improved dynamic range and scale factor linearity performance. These IMUs are developed to affordably meet the needs of a broad range of guidance and control applications. Its small-size, light-weight, high-bandwidth, low-noise, zero-maintenance configuration makes the HG2800 IMUs ideal for electro-optical (EO)/FLIR stabilization, camera/radar stabilization, pointing and positioning, mapping/inspection, autonomous underwater (AUV) and UAV navigation, odometer/DVL, and silent operation for acoustic-sensitive systems.The HG2800 flexible power supply design simplifies system integration for a single +5V supply voltage or dual +15V, +5V supplies, while consuming less power than competing fiber optic gyro-based IMUs in the market.
