| Abstract: | A real-time resolving algorithm for single-frequency precise point positioning is presented.Based on Kalman filter,the observations on single frequency are processed in kinetic situations,and good precision can be obtained without static initialization.Innovation-based adaptive Kalman filter is improved to make the algorithm precise and robust in kinetic situations.In order to correct ionosphere influence effectively,the ionosphere delay on zenith is estimated in filtering process using spherical shell mode... |
