D-3. Orbit Analysis Information Base Concept

Figure D-1 illustrates the information base relationship for Orbit Analysis. The information base includes a database of physical parameters, RGF characteristics, data editing controls, and display formats. In addition, the information base contains a knowledge base, which assists in detection and diagnosis of orbital anomalies. Some code may also be needed for converting tracking data to engineering units and converting between coordinate frames.

Figure D-1 also depicts the layered relationship between the information base elements that can be anticipated in the SSCS application. The first layer will contain information needed for the actual Orbit function to perform for any mission. Subsequent layers address specific data required by each mission area, program, block, and satellite. This information-driven architecture allows a common Orbit Analysis application to support multiple satellite programs.
