  • Global positioning system (GPS) carrier phase cycle slip detection and correction
    Patent number: 9182497
    Abstract: A method and detector for detecting a global positioning system (GPS) carrier phase (CP) cycle slip or correcting the GPS CP cycle slip is disclosed. A GPS CP cycle slip detector can include an integrated CP (ICP) change measurement module, an ICP change prediction module, and a processor. The ICP change measurement module can be configured for generating a measured ICP change of a measured CP of a GPS signal for a time duration. The ICP change prediction module can be configured for determining a predicted ICP change of the GPS signal CP for the time duration using directional position information. The processor can be configured for detecting in near real time a GPS CP cycle slip when the measured ICP change varies from the predicted ICP change by greater than a threshold value.
