The HG1900 is a high performance Inertial Measurement Unit (IMU) designed to meet the needs of a broad range of guidance and control applications. These platforms require high performance under the most demanding environmental conditions. The small size, lightweight, and low power make the HG1900 ideal for tactical guidance applications.
The HG1900 includes Micro-Electro-Mechanical Systems (MEMS) gyros and quartz resonating beam accelerometers. In addition, the HG1900 employs an internal environmental isolation system to attenuate unwanted inputs commonly encountered in real world applications.
Three different performance grades of the HG1900 are available as off-the-shelf items. The HG1900 offers many configurable features, such as data rate output and flight control filtering, to simplify system integration. Honeywell designs, develops and manufactures all of the inertial sensors utilized in the HG1900 IMU. The HG1900 has been successfully deployed by the U.S. DoD and international militaries on a wide range of weaponry, UAV, and platform stabilization applications as well as in commercial applications.
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
