Zusammenfassung:	A method of minimizing a GPS satellite search time in a GPS receiver is provided according to the invention. The method comprises the steps of computing initial conditions that estimate a position of said GPS receiver and that estimate a GPS receiver clock accuracy, computing an initial range estimate, and computing an optimum satellite search order, with said optimum satellite search order computed so as to minimize a search space and minimize a search time needed to find visible GPS satellites.
