Coordinate measurement method and system based on RTK and RTK receiver

The invention discloses a coordinate measurement method based on RTK, relates to the technical field of satellite navigation, and particularly relates to a coordinate measurement method and system based on RTK and an RTK receiver. The base station acquires the first observation data in real time and generates second observation data in combination with the time sequence information for storage, and if the mobile station enters a radio signal blind area and cannot receive the first observation data, the mobile station continuously acquires third observation data and forms fourth observation data in combination with the time sequence information; when the mobile station is connected with the base station through a wireless network, matching data corresponding to the fourth observation data in the second observation data through corresponding time sequence information to form fifth observation data, and performing RTK calculation according to the fourth observation data and the fifth observation data; therefore,
