PROBLEM TO BE SOLVED: To reduce the cost of a real-time GPS surveying system and apply it to a long-term dynamic observation and a positioning survey. ;SOLUTION: In this method, the position coordinates of a measuring GPS survey unit 23A are obtained on the real-time basis based on the observation data sent from a reference station GPS survey unit 22 and the observation data of the measuring GPS survey unit 23A. Two separable external antennas are connected to a GPS receiver 3A provided on the measuring GPS survey unit 23 A selectably by a signal switch 7.;COPYRIGHT: (C)1997,JPO
