| Abstract: | The concept of Real-time Kinematic GPS positioning with virtual reference station has been developed greatly during the past few years.In this paper,the primary principle and construction of VRS system is introduced firstly.Then the methodology of Virtual phase observation generation from VRS network solution is discussed.Besides,the solution model of GPS receiver software after the Differential Correction sent to the user is discussed and results show that the model is identical with conventional RTK.Finally, experiments are taken to prove the reliability and feasibility of the Virtual phase observation generation. |
