| Abstract: | The paper starts with the linear combinations of GPS available observables,analyzing the detection ability of M-W combination and geometry-free phase combination with GPS un-differenced dual-frequency observations,it also discusses the advantage of the two combinations' integration.At last,it also does some experiments to prove the adaptability of ground low dynamic observations and onboard GPS high dynamic observations.All the results indicate that the combined algorithm can do a better applicable and prac... |
