Automated cycle-slip correction of dual-frequency kinematic GPS data

In order to attain high precision positioning and navigation results with GPS, cycle slips must be correctly repaired at the data preprocessing stage. Over the past decade a number of methods have been developed to detect and repair cycle slips. These methods invariably require user intervention for problematic cycle slips in portions of data, tuning of input parameters to data, or introduction of additional carrier-phase ambiguity-resolution parameters in the main data processing where preprocessing cycle-slip determination has failed. A method has been developed from various existing techniques, that provides fully automatic cycle-slip correction at the data preprocessing stage. Results indicate that single-cycle slips can be reliably detected for receivers in varied environments, and that these slips can be repaired correctly.
