Abstract

Carrier phases are always used in precise positioning by global satellite navigation systems.However, the carrier phase measurement may suffer cycle slips during signal tracking. A cycle slip is a discontinuity of an integer number of cycles in the phase observable, caused by a temporary loss of lock in the receiver carrier tracking loop. Thus, the cycle slip must be detected and corrected in order to obtain precise positioning. Several methods have been developed for this purpose. Something that has also been explored is the detection ofcycle slip in the new GPS signals. The advent of the third frequency available from theGPS modernization also It should be explored in the context of cycle slip detection andcorrection. The main goal of this research is implement an adequate method to detect andcorrect cycle slips. Therefore, we intend to develop an efficient system for high accuracyrelative positioning in Brazil, considering the peculiar atmospheric conditions existing inthe country. (AU)
