Honeywell HG1930 IMU

The Honeywell HG1930 Inertial Measurement Unit (IMU) is a compact, high-performance system designed to meet the needs of various applications requiring precise navigation and control. Ideal for military, commercial, and industrial use, the HG1930 provides industry-leading MEMS (Micro-Electro-Mechanical Systems) sensor technology in a small form factor, offering robust performance in challenging environments. Its advanced capabilities make it suitable for applications such as ground and oceanographic surveying, robotics, unmanned aerial vehicles (UAVs), and missile navigation.

Compact and Reliable Performance

The HG1930 IMU combines MEMS-based gyroscopes and accelerometers, providing accurate data even in the most demanding conditions. Its rugged aluminum housing and internal environmental isolation system protect the unit from environmental factors such as shock, vibration, and unwanted inputs. With a minimal size of just 5 cubic inches (82 cm³) and weighing less than 0.35 lbs (0.16 kg), the HG1930 is well-suited for space-constrained applications. The unit also features a low power consumption of less than 4 watts, making it ideal for mobile and battery-powered systems.

Designed for integration with GPS systems, the HG1930 offers integrated navigation capabilities, including PVT (Position, Velocity, Time) and LOS (Line of Sight) data. It is equipped with Honeywell's modular INS software, which supports advanced features like shock compensation, magnetic heading, and barometric altitude, allowing for smoother navigation outputs. The system provides excellent accuracy, with CEP drift of less than 3 meters during a 30-second GPS outage.

Flexible and Configurable for Various Platforms

The HG1930 offers a range of configurable options, including data rates, flight control filtering, and performance grades to fit different application needs. The system is available in three standard models—HG1930CN50, HG1930BN50, and HG1930AN50—each offering varying levels of performance, such as gyro bias repeatability and accelerometer stability. With a wide operating temperature range of -54°C to +85°C and support for both high-speed control (600 Hz) and guidance data rates (100 Hz), the HG1930 is built for diverse environments, from unmanned systems to fixed-wing aircraft.

The unit also includes an RS-422 serial interface, supporting a variety of communication protocols such as Synchronous Data Link Control (SDLC) and asynchronous serial options. The solid-state design ensures long-term dependability, and the system's 20-year storage life minimizes the need for repairs and maintenance.
