Abstract

GPS Positioning has numerous applications in the field of navigation and Geodesy.GPS positioning is mainly based on the different Geodetic Datum. This paper mainly discusses the improved datum conversion equations for the conversion of World Geodetic System (WGS-84) to Universal Transverse Mercator (UTM), vice versa and the reduction of errors introduced while datum conversion. By applying the different filters like Least Squares Algorithm (LSA), Kalman Filter (KF) and Modified Kalman Filter (MKF) a considerable improvement in consistency has been observed. Comparatively Modified Kalman Filter gives better accuracy in positioning.GPS coordinates data samples are collected in different environments like heavy traffic area, tall buildings area are taken to validate the results.
