Short arc optical survey techniques

The effect of the gravity parameter, mu, the choice and local survey of the fixed origin station, and the choice of initial datum on the results of short arc satellite survey adjustments were investigated using GEOS 1 MOTS optical observations from 13 stations. It is concluded that each of these parameters has an effect on derived network scale on the order of 0.000002 for the nominal variations used. A particular solution using assumed best available values for these parameters is recommended.
