Abstract : 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 determine a parametric range distance between the satellite and the observer. Satellite height and range parameters can be reduced to obtain the value for an observed "virtual altitude" (VHo), which is then used in the same manner as the standard Ho measurement.
