国际星基增强系统发展现状及趋势
Development status and trend of international satellite based augmentation systems
摘要
Abstract
In order to promote the application of GNSS in the field of high life-safety,augmentation means,represented by Satellite Based Augmentation Systems(SBAS),have emerged to comprehensively improve the accuracy,integrity,continuity and availability of GNSS service.The United States,Japan,European and other countries have started the SBAS performance improvement work,from single frequency SBAS to dual-frequency SBAS transition,to further improve SBAS performance.This paper summarizes the system composition,service performance,system progress and follow-up development planning of the international SBASs,and focuses on the system architecture,service capability,application verification and internationalization process of BeiDou Satellite-based Augmentation System(BDSBAS).With the implementation of the latest International Civil Aviation Organization(ICAO)Annex 10 to the Convention on International Civil Aviation,BDSBAS has become an internationally recognized provider of SBAS service.Subsequently,to promote the application of BDSBAS in the field of high life safety,it is necessary to complete the verification of civil aviation applications as soon as possible,so that BDSBAS can be included in the official services.关键词
