Detecting Cycle Slips in Carrier-Phase Measurements of Single Frequency Navigation Receivers with Different Instabilities of Reference Oscillators

The use of carrier-phase measurements significantly increases the accuracy solutions when using navigation receivers. One problems in is discontinuities (cycle slips) measurements. existing algorithms detection and compensation cycle slips a singlefrequency receiver either require additional information (for example, Doppler measurements), or operate only differential mode, can detect large slips. purpose research development for detecting small single-frequency receivers without information. We methods filtering trend polynomial adaptive bases, as well modified sparse recovery to estimate difference between code algorithm which used search depends on quality reference oscillator receiver. For with high-stability oscillators (e.g. active hydrogen maser), one trend, result directly detects probability close unity. low-stability (quartz oscillators), minimization total variation applied 1 slip against background noise component comparable magnitude 0.8. results may be systems low stability oscillators, posteriori processing receivers’ correct preprocessing stage.
