  troposphere delay
GPS data are used to define the reference frame, synchronize receiver clocks and determine troposphere delay for the GLONASS tracking network.
      
In the absolute accuracy assessment, the comparison was made in terms of zenith troposphere delay estimation error, with respect to the International GPS Service (IGS) final troposphere zenith path delay (ZPD) product, which was used as the true ZPD.
      
Another potential error source is the wet troposphere delay effect on the altimetry measurement.
      
During this process, the station coordinates can be adjusted, and the vertical troposphere delay is identified.
      
We estimate both a zenith and azimuthal wet troposphere delay.
      


This paper described in detail an one-way timing method via one geostationary satellite when the position of the ground stations were exactely known. The effects of troposphere and ionosphere on radio signal were taken into account and a correction of time delay caused by these effects was made by using a time delay model.Furthemore, this paper laid specific stress on discussing the effect of satellite shift on the timing accuracy and proved that by the use of Square-Interpolate method one can lower the timing...
