【摘要】 为了解决旧GPS设备在JSCORS系统下实现网络RTK的问题,基于通用无线分组业务(GPRS)设计了CORS网络差分模块。该模块采用GPRS/Internet无缝链接技术,通过Ntrip协议的顺从及分析,将其嵌入到模块中,建立了GPS差分数据传输通道。通过大量测试表明该CORS网络差分模块性能可靠。更多还原

【Abstract】 In order to solve the problem of old GPS receiver}s Real-time kinematic(RTK) under the JSCORS system,this paper designed the cors-network communication module based on General Packet Radio Service(GPRS).The technology of joining Internet to GPRS seamlessly and analyzing of Ntrip protocol is used to set up GPS differential corrections communication channel.The experimental results proved that this cors-network communication module had reliable performance.更多还原
