Wide supply voltage range 9 VDC – 32 VDC
Miniature Rugged IP65 Design
Exiguo® EX-300
The EX-300 is a unique , INS/GNSS-Compass system, utilizing 2-Antenna accurate, satellite-based compass – which provide accurate azimuth yaw angle at static & dynamic conditions with enhanced accurate attitude angles.
The EX-300 contains a MEMS-Based GNSS/INS unit. compromising 10-DoF inertial sensors (3-axis accelerometers, 3-axis Gyroscopes , 3-axis magnetometer and a baro-altimeter) along with hi-performance, survey-grade, multi-frequency/multi-constellations RTK GNSS – supporting accurate heading algorithm at static & dynamic conditions, overcoming problematic magnetometer heading systems which suffers from magnetic interferences .
Built-In Unscented-Kalman-Filter algorithm, running on Cortex-H7 floating-point/double-precision processor at 480 MHz clock speed provides static heading solution, PVT along with quaternions, DCM matrix, attitude angles and calibrated. compensated raw data.

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.
