| Abstract: | The mathematical modeling on the mapping function
models should be revised and also simplified to improve the
calculation of the GPS tropospheric delay. The zenith
tropospheric delay can be amplified by a coefficient factor
called mapping function to form total tropospheric delay.
There are many mapping functions have been established to
calculate the scale factor which can affect the total
tropospheric delay. Most of the modern models have
separated mapping functions for the hydrostatic and the wet
part. Recently, the developed tropospheric delay models
use mapping functions in the form of continued fractions
which is quite tedious in calculation. There are 26
mathematical operations for Neill Mapping Function
(NMF) to be done before getting the mapping function scale
factor. There is a need to simplify the mapping function
models to allow faster calculation and also better
understanding of the models. The mapping functions for
NMF models for hydrostatic and wet components are given
in a form of continued fraction, whereby the elevation angle
is the variable. These mapping function models have been
selected to be simplified, because of their ability to achieve
mapping function scale factor, down to 3 degree of
elevation angle. |
