Multi-antenna receiver signal synchronization method in electric iron tower deformation measurement

The invention discloses a multi-antenna receiver signal synchronization method in electric iron tower deformation measurement, belongs to the technical field of electric iron towers, solves the problem of electric iron tower deformation judgment, and is characterized in that GNSS (global navigation satellite system) antennas are respectively mounted on four feet of an electric iron tower footing and are connected with the same GNSS receiver, and the GNSS receiver is connected with the GNSS antennas. The receiver judges the deformation condition of the iron tower by collecting positioning data received by the four antennas. The GNSS receiver is provided with four RTK antenna interfaces, and a working mechanism module for controlling the antennas to collect positioning data in a polling manner is arranged in the GNSS receiver, so that the deformation of the electric iron tower is judged, the system cost is low, and the measurement mode is quick and accurate to realize; the whole antenna switch switching process
