Antenna Pointing & SATCOM OTM
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
Strap Down Installation
To get the best performance, INS and antenna(s) should be installed in the same reference frame. Antenna lever arms should remain the same.
