Use of Common Software Components and Auto-Generated Code at the Example of the Data Services Subsystem in the Columbus Control Centre

摘要

This paper aims at describing principles of software engineering,that were used during development of the Data Services Subsystem(DaSS)within the Columbus Control Center.For this purpose the data services that are typically to be handled within a ground segment are defined and an overview on related data standards is given. rnTo provide a concrete example of such a data handling system,the services, interfaces and architecture of the DaSS are described,as well as the design drivers and resulting design decisions,with the main focus on rn1.The use of auto-generated code for specific purposes(in particular for information exchange via different protocols)rn2.The identification of common functionality and their generic implementation in common componentsrn3.The use of an API to ease development of applications being data providers or data consumers of the DaSS rnFinally,the re-use of components and design heritage in parallel and follow-on projects is described and recommendations are provided to unify further ground segment developments.
