Abstract : In an attempt to solve some of the problems associated with attaining DOD navigation requirements in the 1970's, a constellation consisting of five existing and six future satellites has been developed. Based on the use of these satellites, data coverage studies have been made that include a review of existing data and an analysis of the expected coverage for the future satellites. Expected error budgets have been determined for both satellites and stations. It is concluded that the DOD requirements can be attained. This can be done by improvements in the existing Navy Navigation Satellite System that are well within the present state-of-the art. (Author)
