Abstract
Systems and methods for detecting and displaying cycle slips are provided. In one example method, a first L1 signal and a second L2 signal may be received. The coarse/acquisition code from the L1 signal may be extracted and may be monitored to detect a phase shift in the code. In response to detecting a phase shift in the code, a data bit of the L1 signal may be monitored for a predetermined length of time to detect a change in the data bit. A cycle slip may be detected in response to detecting a change in the data bit during the predetermined length of time. In another example, a cycle slip may be detected in response to detecting a change between a phase of the L1 signal and a phase of the L2 signal.
