ABSTRACT
The system is based on the placement of a receiver, considered as reference receiver at a point well made, very well defined coordinates. The receiver receives the signal from the satellite, calculates distance, and knowing one’s own position and precisely, can cause errors in position, making the difference and on this basis possible corrections.
The paper presents the main techniques of resolving the phase ambiguities as well as the adjustment of the GPS phase observations by least square method within kinematic method, for resolving these ambiguities. The main techniques of resolving the phase ambiguities are presented in terms of the used positioning method and the adjustment of the GPS phase observations is generally presented.
