| Abstract: | The reliability of rate of continuous stations and mobile stations with the GPS long time series and the influence of rate of continuous station was analyzed, considering the different time lengths and starting phases, as well as the rate of mobile station, considering the influence factors of observation cycle and time span. The results show that horizontal rate of continuous station is within ±1mm/a based on 3 4 years’ fitting data,and the variation range of vertical velocity would still greater than ±3mm/a. |
| Keywords: | time series GPS velocity continuous station mobile station reliability |
