Outdoor Navigation System Using Integrated GPS and Pseudolite Signals:Theoretical Analysis and Simulation
The pseudolite augmenting GPS technique can effectively improve the geometric strength of GPS positioning solution,which also enhance the availability,reliability and precision of GPS.Using integrated GPS and pseudolite signals as navigation tools in outdoor situation will contribute to promising application,and there are some obstructions that should be concerned.In this paper,we have a theoretical analysis on some major problems,such as integrated signals modeling, near-far effect,time synchronization and DOP improvement.In the end,the simulations have been presented to verify the relevant conclusion.
