Abstract

Positioning precision aids in calibration of baseline estimation using Global Positioning Systems (GPS) receiver. Analysis of instantaneous epoch measurements improves coordinate positioning than estimation of position using 24-h batch processing of GPS data. In the present work, smoothing of the epoch measurements is done by using Kalman filter to achieve accurate positioning of GPS receivers. Using the above algorithm, the variations in the epoch time are minimized. These variations are caused by receiver loss of lock and cycle slips. These studies will lead to applications in other research areas such as earthquake geodesy and GPS seismology.
