AHRS-200A®
AHRS-200A® is a high precision strip-down AHRS system with which combines
ultra-low noise crystal 3-axis gyroscopes, MEMS 3-axis accelerometer, 3-axis
magnetometer, barometer, high speed MCU and new generation GNSS module in a
single, compact board. All sensors are calibrated over their temperature、bias、scale
factor、axis alignment and g-sensitivity in order to make them ideal for the best
applications.
While moving and when encountering magnetic distortion, AHRS-200A® employs a
patented Kalman filtering algorithm that intelligently fuses with gyros and
accelerometers to overcome errors due to erratic motion and changes in the local
magnetic field to generate optimal Attitude and Heading data outputs.
Application:
- Stabilization platform control
- Aviation control system (UAV, Fixed wing, Rotor, etc)
- Ground vehicle control
- Underwater vehicle control
- Autonomous vehicle
- Robots
Feature:
- Suitable for primary attitude reference
- All solid state components (no moving parts)
- All sensors have temperature、bias、scale factor、axis alignment calibration
- Auto self-calibrate attitude when system fixed and power on
- Enable 1° to 2° compass heading accuracy
- 0.3° heading accuracy with GNSS aided
- Dynamic heading accuracy 1.0° (RMS)
- Overcome errors due to erratic motion and changes in the local magnetic field
- 24-bit ADC digital pressure sensor
- Environmentally sealed (waterproof)
- Small size, light weight and compact design
