Abstract:
A location sensor is a feature that communicates with a Global Positioning System (GPS) receiver to learn about the status of the
current location. This work presents the GPS receiver position estimation and Dilution of Precision (DOP) analysis using a new
approximate form of observation matrix which can be used in place of the classic observation matrix that was derived from the
Taylor’s series. It has been realized that, the approximate observation matrix is numerically stable and provides greater
precision in calculating DOP values and estimating the position of a GPS receiver. The experimental results show that the
proposed observation matrix provides better precision in DOP analysis and GPS receiver position estimation with a fast
convergence rate and improved algorithm stability. Therefore, it can be concluded that the proposed new observation matrix
plays a significant role to estimate accurately the location of the GPS receiver position and to enhance all parameters of the DOP.
