Abstract : For several years the Naval Weapons Laboratory has computed precise satellite ephemerides. he ephemerides, computed for Navy navigation satellites which are accurate to about 5 meters, are widely used for radar calibration and in determining positions of observing stations. The report summarizes computational procedures, coordinate frames, output forms and output formats pertinent to the ephemerides which are produced. (Author)
