A new positioning method (PVD) by a single point GPS receiver is proposed . Since it is a point measurement, a reference point is not required, and it would make possible to build a simple and low-cost measuring system. Carrier wave phases make a high precision measurement possible, but the initial phase ambiguities are not required to solve, when the variation component of the observation point coordinates is the target of the measurement as in the present method. The load of the calculation is not heavy. Hence, it would make a quasi-real-time measurement of high frequency variation possible. However, errors due to satellites are noteliminated at present since PVD is a point measurement, and errors in low frequency regionsmay not be negligible, when the variation of the coordinates is small. Applications to wave measurements by an ocean buoy and earthquake measurements are expected.
