Plane control reference transmission device and method between subway stations based on GNSS static PPP

The invention provides a GNSS static PPP-based inter-subway-station plane control reference transmission device and method, which are used for being matched with a laser transmission shaft and a laser receiving target in a subway tunnel to transmit plane position information of a ground control point into the subway tunnel, and the device comprises a GNSS receiver, a choking coil antenna, a laser automatic leveling plumb aligner and a control module, the choking coil antenna is connected with the GNSS receiver, the output of the GNSS receiver is connected with the control module, and the control module is connected with the laser automatic leveling plumb aligner. The method has the advantages that errors and production cost caused by long-distance guiding measurement of national level control point plane references can be avoided, the method can be flexibly applied to plane connection survey in the subway tunnel construction stage, and the defects that a traditional orientation mode is complex in organization
