The core of the activity is the development and demonstration of technologies to homogenize the data for joint use: this is highly relevant for Atmospheric Sciences data where a large variety of data in terms of sensing time and geometry and dimensionality (1D to 3D) prevent the combined use of various datasets. Nevertheless, the developed methodologies can be applied to other domains, to create meaningful subsets to cope with the growing of the data stream (large amount of EO data coming from different platforms for the same domain).

Integrated Modular Avionics (IMA) is a concept developed for the aeronautics industry to manage the growth in functionality and efficiency required as the industry grows. Integrated Modular Avionics for Space (IMA-SP) is a spin-in of the corresponding concept for spacecraft avionics.

An integral part of the spacecraft development process is the population of the spacecraft database with information related to the interfaces of individual units. This is a significant task involving the manual entry of enormous amounts of data (150,000 items for a typical spacecraft). The content of the information, which is provided by unit suppliers to the Primes, is not standardised and subject to inconsistencies, immaturity and incompleteness, and this is clearly prejudicial to system development.

Global optimisation methods allow finding a minimum on a global search space without restrictions, unlike finding only local extrema. A general mathematical toolbox for global optimisation is not presently available; all existing solvers and solution algorithms are narrowly specialized towards particular problem types or not available in a high-performance implementation. WORHP is a local optimiser, and hence it provides good results when it is restricted to a small search space by a user-provided initial guess.

The definition of the On-board Software Reference Architecture (OSRA) has led to the definition of a main model (the architecture itself, defined in OSRA), supported by other models focusing on specific aspects such as real-time, transaction, bus exchange, etc. or making the link with system such as the Spacecraft Data Base. The space system primes and space software providers have been starting to use various modelling languages (UML or DSLs) and various tools to support their in-house tailored software engineering processes.

The works performed by Savoir-Faire, Savoir-IMA and the related industrial activities have not investigated yet the particular impact of a multicore in the hardware topology on the On-Board Software Reference Architecture. The architectural principles are indeed modular enough to minimize the impacts of the use of a new type of processors. Using a multicore (also in the scope of IMA) in this scope is feasible. But specific aspects need to be investigated:

    State-of-the-art in automated unit/integration testing is a semi-automated approach for which the test environment is established manually, while execution of tests is automated. In contrast to that, the FAST approach already automates building of the test environment and the stimulation of the software, complemented by recording of input-output vectors, observed properties, anomalies and evaluation by metrics and filtering algorithms.

    In the short term, the results of this study shall ease the definition of the new generation of on-board architecture and their verification using representative scenarios. In addition, the results of this study should be taken into account in the definition of a new version of the SpaceWire switches and possibly to provide inputs to the next version of the SpaceWire standard.

    A major challenge in the field of control is to achieve reliable, aggressive, high-speed control of autonomous vehicles. In space, this may involve spacecraft that need to land under harsh conditions, or even – in an extreme scenario – negotiating asteroid debris fields at high speeds. On Earth, the exemplar task that draws most attention currently is high-speed autonomous flight of drones. The application of optimal control on board limited platforms has been severely hindered by the large computational requirements of current state-of-the-art implementations.

    Addressing the utilization of telecommand and telemetry packets for the purpose of remote monitoring and control of the spacecraft, the Packet Utilization Standard (PUS) is one of the few ECSS engineering standards that is applied from the development of the Spacecraft, subsystems and payloads but also in the development of the Ground Segment and to the Operations.Producing a new PUS that includes the last 10 years of lessons learned, the PUS Working Group has applied some formal requirement engineering techniques with as intended objective to enable the capability to automate the productio
