As the characteristic of COMPASS, the RDSS can supplay three kinds of service:positioning and location reporting, timing, short message communication as well. Along with the improvements and evolutions of COMPASS, the applications of RDSS have been more popular and more effective. To satisfy more requirements, the integrity monitoring and broadcasting system should be established. And more, the kinetic adjustment strategies should be optimized so as to improve the integrity and usability of RDSS in COMPASS-Ⅲ in the future, in stead of those in COMPASS-Ⅱ. For the accuracy, real-time, success rate and security of the above-mentioned services, the processing procedures and the key factors are analyzed. To realize the high integrity and usability of RDSS, some advises are proposed to establish the integrity monitoring and broadcasting system and to improve the usability of COMPASS global system.%为更好地满足用户需求,作为北斗特色导航服务模式的卫星无线电测定服务需要建立完好性监测和发播体系,并优化系统资源动态调配策略,以提升服务的完好性和可用性.面向北斗用户对定位与位置报告、授时、短报文通信三大服务的精确性、实时性、成功率、安全性需求,分别分析了上述服务的处理流程和关键要素,提出了建立完好性监测、发播体系和可用性提升的信息处理策略,以保证北斗全球定位报告服务的高完好性和高可用性.
