The answer is ER-MIMU-062.
Surveying in complex terrains such as forests and tunnels can easily cause surveying instruments to fail, thereby reducing surveying accuracy and efficiency.
The core advantages of the ER-MIMU-062 are designed specifically to tackle these challenges:
- Independently measures angular velocity and acceleration
- Minimal size
- Sensor integration
Core parameters:
Gyroscope: bias instability less than 0.03 deg/hr; bias stability (10s 1σ) below 0.15 deg/hr; angular random walk < 0.01°/√h; bias repeatability as low as 0.3 deg/hr.
Accelerometer: bias repeatability only 100 µg; accelerometer bias stability (10s 1σ) less than 50 µg; Class II accelerometer non-linearity below 100 µg/g².
Accelerometer: measures three-axis linear acceleration.
Gyroscope: measures three-axis angular velocity.
Core output: real-time attitude angles, velocity, and position increments calculated through algorithms, providing dynamic reference for surveying data.
