| 摘 要： | 为弥补网络RTK(real-timekinematic)定位模式的不足,提出了一种基于Internet的中央差分定位系
统cenDPS.该系统基于现有网络RTK 的工作环境,由cenDPS服务器端完成流动站端内置的差分计算功
能,大大降低了RTK定位对流动站接收机性能的要求.这种集中式的差分定位系统可实时监测流动站的精确位
置,是位置服务(LBS)领域的重要研究内容和发展方向.试验证明了cenDPS的可行性,系统测试的平均初始化
时间为73s,实时坐标解的精度为cm 级.

| Abstract: | In order to overcome the deficiency of traditional network RTK(real-time kinematic) positioning,a center differential positioning system,cenDPS,was proposed based on the internet.This system is on the basis of the traditional network RTK technology and centers the differential processing on the cenDPS server to greatly reduce the requirement for the rover receiver.This concentrated cenDPS can monitor rover's high-precision location in real-time and is an important aspect for the research and development of ... |
