TRACK SURVEY MODE

In this mode, it needs two or more receivers, one as base, the other as rover. The base station tracks all the visible satellites continously and the rover moves among the points need to survey. It adopts post-processing differential method. In this mode son’t need real-time transmatting data, it won’t be affected by the transfer of electromagnetic wave and the work range extends to 100km. The characters such as high accuracy, long operation range and good reliability and so on, can satisfy different requirements of engineering which don’t request real-time processing. This mode is mainly used in some special occasion such as boudary confirming survey, area survey etc. Work range less than 100 km. Accuracy: mean square erro less than 1 m.
