  • Descrição: Summary Three persistent common problems in satellite ground control software are obsolescence, lack of desired features and flexibilities, and endless software bug fixing. The obsolescence problem occurs when computer and ground equipment hardware become obsolete, usually after only one‐third into the satellite mission lifetime. The software needs to be updated to accommodate changes on the hardware side, requiring significant work of satellite operators to test, verify, and validate these software updates. Trying to help solve these problems, we have proposed an object‐process methodology model and guidelines for developing satellite ground control software. The system makes use of a database‐driven application and concepts of object‐process orientation and modularity. In the new proposed framework, instead of coding each software function separately, the common base functions will be coded, and combining them in various ways will provide the different required functions. The formation and combination of these base functions will be governed by the main code, definitions, and database parameters. These design principles will make sure that the new software framework would provide satellite operators with the flexibility to create new features and enable software developer to find bugs quicker and fix them more effectively.

Conceptual modeling that uses Object‐Process Methodology (OPM), the new ISO 19450 publically available specification, provides a formal, solid basis for the next generation of satellite ground control software. Based on this new paradigm, forward thinking solutions are proposed to lingering problems of obsolescence, lack of desired features and flexibilities, and endless software bug fixing. OPM enables this due to its universal ontology of objects as things that exist and processes as things that transform objects.
