HCM605B Dynamic 3 Axis Electronic Compass Sensor For ROV Underwater Robot Navigation
HCM600/HCM605 is a high-precision 3-axis electronic compass that integrates a three-axis accelerometer, a three-axis gyroscope, and a three-axis magnetic sensor. It dynamically calculates roll angle, pitch angle, and heading angle data in real-time through a 32-bit high-speed processor. The compass has three working modes: pure compass mode, 9-axis fusion mode, and 9-axis fusion anti-jamming mode (anti-temporary interference). It uses a three-axis accelerometer and a three-axis gyroscope to compensate for heading angle errors caused by significant tilt angles and adopts hard iron and soft iron calibration algorithms, ensuring high-precision heading angles within the range of ±180°.
Key features include:
- Heading Accuracy: 0.3°~0.5°
- Roll Range: ±180°
- Tilt Resolution: 0.1°
- Tilt Accuracy: <0.2° (Full Range)
- Wide Temperature Range: -40℃~+85℃
- Dimension: L110×W19.5×H19.5mm
- With Hard-Iron and Soft-Iron Magnetic Calibration and Tilt Compensation
- Interfaces: RS232/RS485/TTL
HCM600/HCM605 is suitable for various applications that require attitude and heading angle measurements, such as:
- Satellite Antenna Search
- Marine Navigation
- Surveying and Mapping
- GPS Integrated Navigation
- Antenna Servo Control
- Infrared Imagers
- Laser Range Finders
- Plotter Mapping
- ROV Underwater Robot Navigation
- Oceanography Measurement Instruments
- Special Occasion Robots
The product is available with or without housing, with the housing offering up to IP67 waterproof protection.
