| Abstract: | The simulation technique of triple-frequency GPS data by using uncombined precise point positioning(PPP) algorithm is proposed.Through solving GPS dual-frequency observation data,the errors of observational environment including troposphere and ionosphere delay are calculated,and then the data of L5 frequency are simulated according to the errors calculated.By the comparison with the measured L5 observation data,it is obtained that the difference between the simulated carrier and the observed carrier is less than 0.2 cycles,and the fluctuation is small enough that verifies the algorithm.Consequently,the simulation technique using PPP could reflect the actual measuring environment and play a significant role in the relevant triple-frequency algorithm. |
