Abstract

When precise GPS positioning is applied in ocean, the baseline length becomes too long, since the reference point can't be placed near. In the present report, a solution for the problem is proposed from a new viewpoint. According to the present method, a possibility for the precise GPS positioning may be developed. In the present report, determination of initial phase ambiguities not influenced by the baseline length is discussed.
