Applications
Gimbal Cameras
The IMU system of the gIMU provides up to 2000 Hz of calibrated, compensated raw data, making it an ideal solution for demanding control applications.
Antenna Tracking System
High Update Rate, low-latency raw data is essential for the control loop of Antenna Tracking systems, The gIMU® provides these needs while withstanding rough environment conditions. Full atitude angles (Roll/ Pitch /Yaw) are available with the aid of built-in 3-axis magnetometer.
