| Abstract: | Global Positioning System ( GPS) have broaden its application prospect in the field of determination of attitude because its advantage and low price.In this paper,considering the determination of the carrier's attitude through GPScarrier phase measurement,the technology of GPScarrier difference is discussed.Focusing on its key technical problem of the determination of carrier phase ambiguity,a method of the fast ambiguity solution is presented.The position of baseline designed,and the arithmetic of determination of the carrier's attitude is introduced.This method defines the preliminary set of ambiguity using the length of baseline,and then eliminates the false answers of the set by constrains. |
