System Design Considerations for Satellite Communications on the Move

Abstract:

Communications on the Move (COTM) has gained a great deal of attention recently. The need for broadband connectivity from a moving vehicle has increased dramatically in the past few years for both commercial and military applications. This paper will discuss elements and considerations of providing satellite communications on a moving platform from a system perspective. It will focus on Internet Protocol (IP) over satellite since IP has become the dominant protocol for newly deployed voice and video applications. A global COMT network has much great degree of complexity than a regional network since it will require beam switchover and IP routing re-convergence as a vehicle moves from one satellite beam to another. This paper will present some approaches to COTM system design including antenna size and link budget, spectral density, the Doppler effect, beam and teleport switchover.
