Method of determining the integral wave phase in a geodetic interferometry method
First Claim
1. An improved geodetic interferometry method including the steps of setting a pair of GPS antennae at a fixed known point and an unknown point, respectively, and receiving L1 band radio signals transmitted from at least one satellite with the GPS antennae at the same time to determine the distance and bearing between the known point and the unknown point, wherein the improvement comprisesdetermining the integral wave phase by the steps of:
- sequentially positioning the GPS antenna of the unknown point at two locations which are equidistant a distance r and 180°
opposite each other with respect to the other GPS antenna that is positioned at the known point, anddetermining the integral wave phase based on the L1 band radio signals received at the two 180°
opposite positions from the satellite in a manner that is independent of the length of distance r.

Abstract
In a geodetic interferometry method, a pair of GPS antennae are set at a fixed known point and an unknown point and radio signals transmitted from a plurality of satellites are received at the same time with the GPS antennae to determine the distance and bearing between the known point and the unknown point. In this process, the GPS antenna at the unknown point is sequentially set at two positions which are equidistant and 180° opposite each other with respect to the GPS antenna set at the known point and the integral wave phase is determined from the radio signals received from the satellites at these two positions.
