Antenna Pointing & SATCOM OTM 

Inertial Sensors for Antenna tracking systems and SATCOM On-The-Move (SOTM)

The Inertial Navigation System (INS) provides real-time position, roll, pitch, and heading used for steering the antenna toward satellite direction.

These navigation data are required by antenna tracking systems on moving platforms. The integrated Extended Kalman Filter gives a consistent and robust solution for pointing in case of GPS/GNSS outages, multi-path, jamming, or spoofing.

The internal IMU outputs high frequency sensor raw data and filtered orientation (Pan/Tilt) to stabilize the antenna by removing rapid vehicle motions and thus, maintains the Line-of-Sight (LOS) with the Satellite.

Tips

To get the best performance, INS and antenna(s) should be installed in the same reference frame. Antenna lever arms should remain the same.

Ellipse Micro IMU delivers 1,000 Hz raw data for precise real-time turret stabilization.

SBG inertial sensors are highly resistant to shock and vibration. They also embed specific algorithms to filter vibration. When choosing the right inertial sensor, note that the A3 accelerometer (16g) is the right option for harsh environments.
