An alternative strategy for Triple-frequency Multi-GNSS cycle-slip detection
Future GNSS constellation will contain more than 120 satellites,and the number of frequency bands are gradually increasing.Multi-constellation GNSS positioning has shown a broad development prospects.In order to meet the increasing demand of multi-frequency multi-constellation,this paper presents a data pre-processing scheme,which is used to detect cycle slips of triple-frequency multi-constellation observations.This method is integrating triple-frequency ionosphere-free observations,dual-frequency G-F observations and dual-frequency M-W observations to detect cycle slips with TurboEdit method.The specific detection method is polynomial fitting,which weaken the noise level of the observation and improve the efficiency of detection.The combination coefficient of the triple-frequency ionosphere-free observation is deduced from the least-squares adjustment.The triple-frequency detection method is established while the traditional dual-band detection capability still remains,to meet the needs of both dual-frequency users and triple-frequency users.The experimental results show that this method is able to detect the obvious cycle slips,and improve the quality of the observed data.
