R. B. Gunderman,K. B. Williamson especially in urban canyon environment, has received much attention in academic and industrial circles. In order to get multipath model in the real urban canyon environment, the real GNSS IF signal data is collected in Shanghai typical urban canyon area. Code phase delay, carrier phase changing rat

Introduction to Nuclear Medicineompared for various solar activity conditions and different latitudes for China and around areas. It shows that the ionospheric anomaly in low-latitude areas impacts the variogram seriously, causing a larger intercept at zero distance and a “bump” at the distance of about 1000 km. An alternative met

Apart from the redundant observations of the receiver are used for RAIM, there are various parameter information provided form receiver and the receiver clock error is one of them. As the stability of the receiver oscil

Introduction to Nuclear Medicineme Slot (FTS) is proposed for GNSS constellation in this paper. Firstly, we model a GNSS constellation network as a FTS, where each time slot corresponds to an equal-length interval in system period of the GNSS network. Then, we formulate link assignment as a mixed integer linear programming problem
