특징
- Sensors and processing
- Excellent gyro bias stability over temperature
- Adjustable low-pass filter and EKF settings provide customizable performance for various applications
- States and sensor data synchronized to GPS position and velocity using optional external GPS module
- Allows for alignment calibration and third-order bias and scale factor temperature compensation for accelerometers, gyros, and magnetometer
- Magnetometer soft and hard-iron calibration can be performed through the CHR serial interface software
- Communication
CHR Serial Interface. Graph of quaternions displayed by the CHR Serial Interface connected to a UM7/UM7-LT orientation sensor. - Output data:
- Attitude and heading (Euler angles)
- Attitude quaternion
- magnetometer, accelerometer, gyro data
- GPS altitude, position, velocity (with optional external GPS)
- 3.3 V TTL serial interface (UART) with baud rates up to 921,600 bps can stream data or provide updates on request
- Note: the main UART pins, TX, and RX, are 5V-tolerant and can be directly connected to 5 V systems that are guaranteed to read 3.3 V as high
- Transmits data using human-readable NMEA strings (up to 100 Hz broadcast), binary packets for higher efficiency (up to 255 Hz broadcast), or a combination of both
- Flexible communication architecture allows UM7 to transmit any combination of data at individually adjustable rates
- Connects to the CHR Serial Interface software to allow for real-time plotting of sensor data, logging, device configuration, and magnetometer calibration
- SPI interface available through expansion connector
- Output data:
