| Abstract: | Cycle slips detection and reparation is a key task in the processing of GPS Carrier-phase data.Firstly,dual-frequency differenced Carrier-phase method was introduced.Then,the computation procedure for this method was developed.Furthermore,experimental results,which were carried out using real GPS data with different sampling interval,were analyzed and discussed.Finally,disadvantage of the method was discussed. |
