This paper developed a new approach to improve GPS carrier phase measurement, for the purpose to reduce the ambiguity integer value or use it in time transfer technology.

The basic idea of tracking pointing inconsistency correction using GPS carrier phase was presented.

The principle of surveying the transformation of high-rise buildings by using the technology of the global positioning system(GPS) is introduced,and the test processes of simulation and observation are described.

By applying the strobe correlator used widely in global positioning system(GPS)scenarios to Galileo E1 signals,it can be found that the strobe correlator has an undesirable level of performance when the delay of multipath signals is about 0.

Considering the nonlinear characters of the global positioning system(GPS),an extra Kalman filter is used to calculate state prediction value.

An efficient cycle slip detection method is proposed for high precision positioning and navigation results with global positioning system (GPS),which is based on the assumption of a high sampling interval, measurement errors are so small that they can be ignored in the temporal single difference observables.

With interconnection of power system, inter-area low frequency oscillation has become one of the serious factors affecting interconnected power system stability, while the application and development of wide-area measurements based on Global Positioning System (GPS) have provided a new approach for controlling of low-frequency oscillations.
