Description
Summary:This paper is aiming for cycle slips detection and correction by combining code-phase combination method with Geometry-free phase combination method. Firstly, taking the advantage of the Geometry-free method which is good at detecting small cycle slips to elect two combinations to construct the first two detectable amounts; Secondly, using the triple-frequency code-phase method to construct cycle slips detectable amounts, at the same time, selecting one optimal combination of cycle slips as the third detectable amount. Finally, combining with three cycle slips detectable amounts to construct a linearly independent equation, after that, solving the equation to repair the cycle slips. Simulation results showed that the method can effectively detect both large and small cycle slips, it can also repair cycle slips quickly.
