Research on the Mapping Functions for Tropospheric Delay Model
Abstract On the basis of introducing the empirical mapping function NMF and the dynamic mapping functions VMF1 and GMF, using one year’s grid data provided by ECMWF, the time varying characteristics of these three mapping functions and their variations with height, latitude and elevation angle are concretely researched and analyzed are compared. Finally,we compare the influence on slant path delay with the variations of elevation angle in the three kinds of mapping functions are compared.
Key words :
GPS data processing
tropospheric delay
slant path delay
mapping function
temporal and spatial variation
