The Operational Adoption of the EGS-CC at ESA

This paper describes an analysis of the formalization of contracts between components in component-based frameworks. The long term objective is to describe each component of the framework in an accurate and selfstanding manner so that the description can be used a) to design and code them in isolation and b) to enable the derivation of test cases to validate them against the formalized description. As part of this analysis several existing approaches (such as the Gherkin language and the concordion framework) were investigated. Based on the results of this investigation, a custom-made toolset was designed and prototyped. The prototype relies on two different approaches to describe the formalized contract: a) The Unified Modelling Language (UML) used together with the tool Magicdraw and b) a purpose-build Domain Specific Language (DSL) defined on top of the Eclipse framework. A small proof of concept was designed to illustrate the approach and the specifications created using those two approaches were automatically converted into tests and executed.

Automated derivation of tests from specifications

“…While considerable progress has been achieved so far, on-going as well as future developments reside in the areas of automation of the systems deployment and configuration to fully enable continuous integration and testing, test automation to include automated problem root cause analysis and forecasting, security testing, and collaborative environment. In addition, while the E2E GSRF is evolving towards the future ground segment architecture based on new major developments, in particular European Ground Segment Common Core (EGS-CC) based Monitoring and Control (EGOS-CC) [8], the convergence of the various integration and test environments used throughout the systems engineering lifecycle is pursued, in particular by extending the E2E GSRF together with the Science and Space segment.…”

The ESOC End-to-End Ground Segment Reference Facility

The Ground Segment for Mission Operations is a complex System of Systems, including a significant variety of complex elements, often generic and reused across missions, following adaptation to meet mission or family of missions specific requirements and configuration. For such Systems of Systems, the availability of a reference environment where individual ground segment components can be deployed and tested throughout their lifecycle, both at subsystem level and in integrated test chains up to a complete End-to-End Ground Segment, is critical. Also the representativeness of such an environment is critical, in particular the representativeness of the test scenarios with respect to the end-user use cases. At the European Space Operations Centre, the End-to-End Ground Segment Reference Facility has been established as the one-stop environment where the System level Integration and Testing of the Mission Operations Infrastructure takes place. This paper provides an insight into the technical aspects of the End-to-End Ground Segment Reference Facility, the latest achievements, an overview of the remaining challenges and the outlook of its intended evolution.

“…At ESOC in particular the ESA Ground Operation System Common Core (EGOS-CC) is developed by integrating additional ESA-specific components with EGS-CC. [2] This forms the basis for full systems that will eventually be ready to be used operationally, one particular example being the mission control system for the Jupiter Icy Moons Explorer (JUICE), which is currently planned for launch in 2022. [3] A lot of integrator activity during this phase is focused on testing the delivered EGS-CC based Test System Instance and these tests can be quite involved and take a long time.…”

EKSE: A Command Line Interface for EGS-CC based Systems

Schiller¹

2018

Until recently, the interaction with systems based on EGS-CC (the European Ground Systems Common Core) was limited to the graphical user interface developed as part of its reference implementation. However, the need has been identified for an interactive console to interface the system. Several approaches for such an interactive console have been considered and will be introduced in this paper. The approach finally chosen is referred to as EKSE (EGS-CC Karaf Shell Extension), which enables users to define commands based on scripts which can even be created at runtime, enabling fast prototyping for interactions with the backend. Particular challenges will be highlighted and approaches for meeting them will be proposed.
