Cycle slip detection and repair with a circular on-line change-point detector
The aim of this article is the processing of angular data, with application to GNSS signals phase and frequency estimation. We propose a circular particle filter for the processing of angles in case of non-linear state/observation equations. We propose a circular change point detector for the processing of abrupt changes in angular data. We propose a phase open loop and a frequency semi-open loop for the tracking of GNSS signals. The proposed methods are assessed on synthetic data for phase and frequency estimation and on real data for positioning application.
