| 摘 要： | 该文以单频GPS接收机为基础,以RTK(实时载波相位动态测量)为目标,通过丈量短基线、交换天线,以及前后载波相位观测值的处理,在2min内解算出具有足够精度和可靠性的整周模糊度.失锁时利用失锁前最近的定位点再次初始化,由此实现的差分GPS动态定位精度可达平面误差бP≤±5cm,高程误差бH≤±10cm.可广泛应用于工程测量、放样、测图,实例证明,在水土保持、林业资源调查、环境监测中亦有广泛的应用.

| Abstract: | Based on the use of mono frequency GPS receivers and aimed at RTK (real time kinematic), the paper discusses how to compute ambiguity with sufficient precision and reliability within 2 minutes by measuring short baseline length and dealing with the difference between carrier phase received by transfering antenna.When unlocked, initialized again using the latest positioning point prior to unlocking. The precision of the differential GPS kinematic positioning is as follows: plane error\ б P≤±5 cm;altitute error б H≤±10 cm.This method can be widely used in engineering survey, layout,map and has a broad prospect in soil and water conservation ,the survey of forestry resources and environment monitoring, which has been proved in practice. |
