Abstract
Range and,interferometric observations have been

examined for their potential, application in a geometric

approach to determination of satellite ephemeri. The

approach differs from the normal (dynamic) approach in that

each satellite position is treated as an independent state

variable or benchmark.

Programs have been developed that simulate and format

the input, data for the least squares estimation routines,

and perform statistical analyses of those results. Random error, tropospheric refraction errors, and atomic clock errors have been considered, and the range observation adjustment program directed to solve for clock errors.
