卫星导航系统上行注入的研究现状与发展趋势
Research Status and Developing Trend of Uploading Schemes for Satellite Navigation Systems
摘要
Abstract
An uploading system is an indispensable part of a satellite navigation system because it is a life-line of the system. This paper studies the uploading schemes used by foreign global and regional satellite navigation systems. Global Positioning System( GPS) is transiting from GPS II to GPS III. GPS II uses a signal-satellite direct uploading scheme and sets uploading sites globally. But GPS III will use a scheme based on data transmission via its inter-satellite links and sets sites only in USA. Galileo uses the same scheme as GPS II. Russia's Global Navigation Satellite System( GLONASS) and Quasi-Zenith Satellite Sys-tem( QZSS) and Indian Regional Navigational Satellite System( IRNSS) use the signal-satellite direct up-loading scheme and set native sites only. Today,with the studying,scheduling and developing inter-satel-lite link of global systems,the scheme based on inter-satellite links will certainly become a trend of the up-loading scheme of a global system and a cooperation among uploading links and a high-speed transmission will be key technologies inevitably.关键词
