摘　　要：为了进一步加强区域地基增强系统互联互通,满足跨区域用户的高精度定位需求,提出一种CORS跨网漫游服务方案,基于该方案设计和实现了跨网漫游服务平台,并对平台功能和漫游服务性能进行测试。测试结果表明,平台可实现跨网漫游服务无感切换,漫游初始化时间较非漫游略增加3 s~5 s,差分龄期和定位精度与非漫游一致。In order to further strengthen the connectivity of regional ground-based augmentation system and meet the high-precision positioning requirements of cross regional users,a cross network roaming service method of CORS system is proposed.Based on this method,a cross network roaming service platform is designed and implemented,and the platform function and roaming service performance are tested.The results show that the platform can realize the cross network roaming service without sense switching,the initialization time is slightly increased by 3-5s,and the differential age and positioning accuracy are consistent with non roaming.
