Abstract: The present work mainly focused on the positional accuracy of Global Position System (GPS). Wherein, the calculations are done on the basis of transit time of each satellite. The individual satellite time is corrected through GPS time with keplerian and time parameters of visible satellites. Different satellites ephemeris data are collected to estimate their transit time for each second. These transit time corrections are done for all visible satellites with reference to ground based GPS receiver, from which the position of satellite is determined. This positional accuracy will be useful for precise navigation.
