Abstract : The initial objective was the proof of the concept, which was accomplished with the following steps. (1) Assume a potential model as the truth potential, e.g., a simple potential with 1000 mass points. (2) Generate truth satellite orbits from the potential of Step 1. (3) Using the orbits from Step 2, extract observations. These observations of the truth model may be used to calculate a best alternate potential model in a least squares sense. The alternate model is a point mass model with 100, 200, 500, etc. total mass points. (4) Compare the orbits generated from the model potential with the orbits generated from the truth potential. As was reported in September 1996, the proof of the concept phase did validate or refine most of the basic ideas and suggested a clearer future course of action.
