The Navigation of a Communication Satellite
Journal of Navigation, 1963The navigational aspects of the requirements for a medium altitude satellite communication system are discussed. Twelve satellites have to be injected into a circular equatorial orbit with very great precision. It is not practicable to navigate the launching vehicle accurately enough to obtain the correct orbit at first injection and the satellite ...

Use of satellites for navigation
IEEE Transactions on Aerospace and Electronic Systems, 1968Any position on earth can be determined as the intersection of two circles, with their centers located at 0 and 0' on the earth's surface just beneath two satellites. Therefore any flying path can be described as a locus of many such positions. One synchronous satellite can cover 45 percent of the surface of the earth.

SATELLITE CELESTIAL NAVIGATION
1967Abstract : Satellite range and location data can be used to determine the location of an observer. This report discusses how the above may be done by using conventional celestial navigation methods. In lieu of sighting with a marine sextant or a bubble octant to obtain an observed altitude (Ho), a receiver and a phase-measuring technique can be used to
