主　　题：Pulsar navigation Position determination Phase cycle ambiguity Geometric dilution of precision(GDOP) 

摘      要：Pulsars are rapidly rotating neutron stars that generate pulsed electromagnetic radiation.A new method for intersatellite relative position determination between a global navigation satellite system(GNSS) and spacecraft using X-ray pulsars is proposed in this *** geometric model of this method is formulated,and two different resolution algorithms are introduced and *** phase cycle ambiguity resolution is investigated,and a new strategy is proposed and *** the direct vector parameters of the pulsar,geometric dilution of precision(GDOP) is *** is shown that this method has advantages of simplicity and efficiency,and is able to eliminate the clock *** analytical results are verified numerically via computer simulations.
