“…Such models are developed for different parts of the globe by several investigators (Hopfield, 1971;Saastamoinen, 1972;Bevis et al, 1992;Schüler, 2001). A similar empirical model developed for the Indian region was discussed in detail by Saha et al (2007). These models are more suitable for the static GPS stations, where collocated atmospheric measurements are available.…”

“…The second column of Table 4 shows the mean absolute deviation between the estimated slant delay and true slant delay, with standard deviations shown within the parenthesis, for the period 2001-2003. In the second approach, the ZHD is estimated using the Unified model developed (Saha et al, 2007) to suit for any location over the Indian subcontinent using 8 well distributed stations over this continent, with measured surface parameters as the input and site-specific Tropo-Chi function is used to project this delay into a slant path (w=851) which is compared with the true slant delay. In the third approach, the zenith hydrostatic delay is estimated using the IRTD model (Parameswaran et al, 2008) and projected it into a slant path (w =851) using site-specific Tropo-Chi function and compared it with the true slant delay.…”

“…Valoraron la sensibilidad del ZTD respecto a la máscara de elevación, sobre todo con ángulos pequeños y con las nuevas mapping functions desarrolladas. Saha et al (2007) estudiaron el retraso troposférico en la propagación de la señal GPS para una atmosfera tropical en la India.…”
