摘　　要：面向大规模全球卫星导航系统(GNSS)基准站网和差分定位用户同时接入GNSS差分服务系统的需求,为解决1000个以上GNSS基准站实时数据流处理和5000个以上差分用户实时服务问题,该文提出微服务调度和维护模式,合理设计了大众位置服务云平台的架构及功能,初步构建了位置私有云平台,开发提供了位置服务产品。并对云平台进行了大规模并发用户接入性能测试,测试表明大众位置服务云平台具备同时管理和并发接入基准站数据流超过3000个,单格网区域可同时服务用户超过5000个。以湖南省为例,大众位置服务云平台设计3个服务格网,可同时服务在线并发用户数超过130000个。For mass global navigation satellite system(GNSS) reference station network and differential positioning user access GNSS difference at the same time the demand of the service system, in order to solve more than 1 000 GNSS reference station real-time data stream processing and more than 5 000 difference users real-time service problems, micro service scheduling and maintenance mode was put forward, the architecture and function of public place cloud service platform were reasonably designed, private cloud platform was preliminary built, and location service products were provided. A large-scale concurrent user access performance test was carried out on the cloud platform. The test showed that the mass location service cloud platform had more than 3 000 data streams for simultaneous management and concurrent access to the benchmark stations, and the single grid area could serve more than 5 000 users at the same time. Taking Hunan province as an example, the mass location service cloud platform designed three service grids, which could simultaneously serve online and had more than 130 000 concurrent users.
