The DRS Ku-Band Satellite Communications On-The-Move

(OTM) Antenna System is designed for continuous high

bandwidth voice, video and data in a highly dynamic

environment. The design approach provides an affordable

on-the-move solution combining a rugged mechanical

architecture with highest quality Commercial-Off-The-Shelf

(COTS) components for vehicle, shipboard and aircraft

applications.

The design is based on proven technologies integrated into

a complete on-the-move package. Integrating navigation

sensors, control electronics and Radio Frequency (RF)

equipment on the pedestal provides improved stabilization,

acquisition and tracking performance. The combination of

open-loop pointing, closed-loop tracking and software

algorithms for sensor fusion enable high performance in

an affordable architecture.

This solution is also available in Ka-Band and X-Band

upon request.
