A New Continuous Time and Frequency Transfer Algorithm Based on GPS Single Different Carrier Phase Observations

  • The characteristics of GPS Common View(GPS CV) and GPS Carrier Phase time transfer(GPS CP) methods are introduced,and a new continuous time and frequency transfer algorithm based on GPS single Different Carrier Phase observations is proposed.The new algorithm uses an ionosphere-free combination of single but different observations from the same satellite and the processing steps are also consistent with simple traditional GPS CP.But,the Bayesian estimation of prior information is proposed to smooth the day-boundaries of time transfer results.Simulation results,which compared to that of GPS CP method,show that the proposed new algorithm improves the precision and frequency stability of the time and frequency transfer results remarkably.
