Product Overview
The Honeywell HG1120 is an Inertial Measurement Unit (IMU) designed for industrial applications such as agricultural vehicles, robotics, survey, mapping, and stabilized systems. It measures angular rates, linear accelerations, and magnetic fields in a body-mounted, strap-down configuration. The IMU provides compensated incremental angle and velocity data for navigation, as well as angular rates and linear accelerations for control. It utilizes MEMS gyroscopes and accelerometers, along with necessary electronics and software for precision control and navigation. The input axes form a right-handed frame aligned with the IMU mounting frame. This No License Required (NLR) IMU is suitable for air, land, and sea applications, leveraging Honeywell's long-standing expertise in gyro production since the 1940s and MEMS technology since the early 2000s.

Technical Specifications
| Parameter | Description | Details |
| Measurement | Angular Rates, Linear Accelerations, Magnetic Fields | Body-mounted strap-down configuration |
| Output Data | Compensated incremental angle and velocity (navigation), Angular rates and linear accelerations (control) | Digital serial interface bus, available in various serial formats |
| Internal Components | MEMS gyroscopes, MEMS accelerometers | Electronics and software for precision control and navigation |
| Interface Protocols | Asynchronous, SPI, CAN 2A/2B | Configurable via DIO1-DIO4 pins (read upon reset/power up) |
| Power Requirements | Input Voltage: 3.0 5.5 VDC | Power Consumption: < 0.4 Watts, 125 mA. Input voltage should monotonically increase at start with ripple < 30 mV P-P. |
| Control Data Bandwidth (-90 Phase Point) | Varies by protocol and data rate | Nominally 97 Hz (Gyro), 155 Hz (Accelerometer) for 1800/300 Hz ASYNC; 90 Hz or 50 Hz for 600/100 Hz ASYNC, SPI, CAN |
| Data Rates | Control/Navigation: 1800/300 Hz or 600/100 Hz | Control data filtered and sampled at 1800 Hz, decimated for 600 Hz control data. Navigation data is unfiltered 1800 Hz sensor data summed to navigation rate. |
| Serial Output FIFO | LS byte first, LS 16-bit word first | Sensor data (gyro, accelerometer, magnetometer, temperature) are signed 2s complement integers. |
