Performance analysis of navigation by the integration of GPS-24 with LEO & GEO
An integrated network consisting of GPS-24 (global positioning system), LEO (Low earth orbit) and GEO (geostationary earth orbit) is analyzed in order to find the position coordinates of a GPS receiver or user position by calculating the position coordinates of GPS satellites. The integrated network is designed to extend the coverage area of GEO satellites up to the polar regions as well as to improve the user position accuracy. Satellite visibility through GPS receiver has been investigated using complex simulations of failure scenarios by giving shadow effect. An algorithm is proposed to estimate the userpsilas position from the known parameters of GPS satellites. Numerical analysis is carried out for the selection of best four satellites to be used for the calculation of userpsilas position. A new approach is also developed for the determination of minimum dilution of precision (DOP) using such integrated network.
