摘　　要：卫星导航系统RNSS服务区定义了系统可为用户提供导航、定位、授时服务的区域范围，是系统标准定位服务中需向用户承诺和声明的一项重要指标。本文通过对北斗区域系统星座几何及用户等效距离误差的分析和综合，给出了经纬度范围形式的理论服务区和基于监测站定位结果的实测服务区，为北斗标准定位服务规范的制定提供了服务区划分技术支撑。The service area of navigation satellite system demarcates the region in which the service of navigation, positioning and timing can be provided. It is an important specification of the standard positioning service which needs to be committed and declared to users. Based on the analysis of PDOP and UERE of the BeiDou regional navigation satellite system, the latitude and longitude values of a theoretical service area and the measured service area obtained from the observation of monitoring station are presented, which provide technological support for the division of standard positioning service area of the BeiDou regional navigation satellite system.
