Abstract:	To investigate the effects of dynamic solar panel and thermal radiator movements on the Space Station GPS carrier phase measurement, a new computer modeling approach is proposed. This new approach is accurate and significantly reduces the required computing time for the conventional computer modeling technique by separating the dynamic structure elements from the static structure elements in the multipath computations. Results obtained from this study indicate that this new computer modeling approach reduces the computing time considerably, by more than 30%, and only very slightly decreases the accuracy of the percent coverage of the GPS receiver antenna gain and phase shift patterns.
