MoBaTe – Enabling Model-Based Testing and Automated Test Case Generation for Ground Segment Data Systems

The driver behind the MoBaTe activity was to propose ways to improve the current software development and validation lifecycle using MBSE techniques to shift some of the system validation activities to the early stages of development. The roadmap to achieve this included identifying strategies, required model properties, modelling tools and languages needed to move from a requirements-based approach to a model-based approach. All this considering existing and established workflows and tools currently used by ESA.

Early in the loop MBSE assessment of electronic availability for nano/micro-satellites (ELMASAT)

The main objective of the ELMASAT study was to brint into Capella the means to calculate the availability of a satellite system and provide extra facilities for trade-off analysis. As an example of application, an assesment of SEE detection and mitigation strategies was performed with respect to availability objectives.

Investigating spectroscopy and forward model improvements for atmospheric retrieval of methane in the thermal infrared

The aim of this study was to explore and consolidate the possible sources of methane biases in retrievals from thermal infrared sensors, to establish necessary actions and perform the related work for mitigating biases. The study distinguishes three types of error sources, which shall be covered: spectroscopic knowledge and input data to radiative transfer models, forward model errors, and instrument biases.

REACH into LCA – Integration of REACH and CRMs into the Life Cycle Assessment framework

For the REACH assessment, the proposed method relies on both ESA’s existing Life Cycle Assessment (LCA) framework and the Materials & Processes Technology Board (MPTB) database. Then, the method was structured through three steps:

  • Firstly, a commonality was found between the LCA and MPTB databases: ECSS classes, which help define small groups of materials defined as 'clusters', are used to 'bridge the gap' in terms of level of precision between the LCA model of a space system and the MPTB database;

Impact of controlled and semi-controlled re-entry on Spacecraft design

There is increased attention being given to safeguarding Earth's orbital environment, as reflected by the number of relevant regulations that are being set forward by national governments and international organisations. Among others, ESA has published a Space Debris Mitigation Policy for Agency Projects (ESA/ADMIN/IPOL(2014)2), supported by the corresponding ESA Space Debris Mitigation Compliance Verification Guidelines (ESSB-HB-U-002).
