Abstract:

The general definition and error propagation law of the combinations of GPS carrier phase observations are given and the features of several special combinations of GPS carrier phase observations are discussed. Then matchable definition and matchable necessary and sufficient conditions of the combinations of GPS carrier phase observations are presented.

Key words: GPS, carrier phase, combinat ions of GPS carrier phase observat ions, erro r p ropagat ion
