Study of navigation accuracy for the proposed QUASAT mission
Abstract
A covariance analysis has been performed for the proposed QUASAT, an earth orbiting radio telescope. Conventional (Doppler and range) and advanced (diifferenced and doubly differenced one-way range) radio metric data types are used to evaluate the navigation accuracy that can be achieved. It is found that the mission requirements are met by conventional data types, while advanced data types can provide an order of magnitude improvement with less measurements, provided the three NASA DSN stations are augmented by more closely spaced stations.
