摘要：

This paper covers the analysis of (reference) position estimation procedures in the navigation application domain, discovering of potential weaknesses and suggesting the improvement. The algorithm analysis involves practical performance and rating of the algorithm performance quality using measured pseudorange. For the empirical comparison, we used GPS receiver's observations collected from IGS reference station located in Padua, Italy. We present a quantitative performance comparison of the modified and the standard algorithm, based on simulations conducted in R environment for statistical computing.
