Title   Design and Analysis of Servo system    Of vehicle satellite communication in motion
Abstract
Accompanying with the progress of society and Information Technology, COTM
（communications on the move）has arisen in people’s growing demand for
communication on the move via Satellite Networks. The technology of
communication on the move via satellite networks, known as COTM, with the
core of fast, stable, reliable servo control technology, is focusing on
establishing a stable platform to ensure that the antenna on the motion
carrier is always pointing the same direction. Currently, Servo control
technology is one of hotspot as well as difficult spot in the application
area of COTM technology.
Based on the study of servo control subsystem of car carrying COTM via
satellite networks, this paper makes a research on the overall design
scheme, hardware design scheme, software design scheme of the antenna servo
control system, as well as gives a detailed introduction to the design an
implementation of the stability and tracking system. In the hardware
design, this paper introduces the basic principles and compositions of the
two system for the selection of key devices, and analyses the control theory
and algorithms of the amplified circuit module as well; about software
design, the system is mainly pided into four parts: initialization
module, module, information of satellite attitude algorithm module and the
automatic tracking module.
