Abstract: An investigation is carried, to study the position estimation algorithm by a receiver using GPS satellites. The RINEX version 2.11 data were used for the analysis as input to test and establish an algorithm. The obtained position from the mathematical algorithm was compared with the reference position. Dilution of Precision (DOP) estimation is also carried out to analyse the geometry of global positioning system (GPS) satellites as observed by the receiver and its effect on position estimation. It is observed that, using a position estimation algorithm that is developed for this study, a good estimate of location is obtained and is found matching with the reference values closely and exhibited better estimates if compared with portable GPS receiver measurements. The results obtained after processing RINEX data shows the difference close up to 6th decimal places or up to centimeter-level for latitude and longitude.
