Transformation of Neill Mapping Function For GPS Tropospheric Delay

The refraction of the Global Positioning System (GPS) signal as it passes through the neutral atmosphere from the satellite to the earth can be referred as GPS tropospheric delay, which causes longer distance traveled by the signal. The tropospheric delay is the product of zenith tropospheric delay...
