Description of the work during First period
Since the beginning of the project, the consortium has defined and described the specifications and ensured his compliance along the design phase. From these requirements, collected in the System Requirements Report, the designers and specialists started to work on the technical solution. They designed and detailed a product in three phases: a high-level overview of IMASAT system main hardware and software parts, conceptual design, and a preliminary design with a deeper insight in the system and the final design of the system that meets customer requirements as well as standards and regulatory requirements.
(Figure 4 - HW-SW levels)
In this sense, a full analysis of the system has been performed to prove that system requirements have completely and correctly been understood and that all technical requirements are implemented. Simulations thermal and vibrations have been carried out and a safety analysis has been performed to prove the reliability of an IMASAT node.

Concerning the test bench, its technical, performance, operational and support characteristics and the external communication interfaces have been defined in order to be able to debug the hardware and software assumptions

During the 2nd reporting period.
it has been reached to an agreement on the environmental tests to be performed, by prioritizing TM (Topic Manager) and CLUE needs, confirming the tests’ categories, considering the necessary auxiliary equipment, and scheduling the laboratory tests. Three companies were requested for quotation and schedule estimation on the agreed environmental tests.
it has been attained an agreement on the form and contents on PikeOS training provided by SYSGO.
IMASAT Computing Node prototype and its Test Bench have been developed/manufactured (Figure 7 and Figure 8). Three versions of the Computing Node have been developed (v1, v2, new version).
the Built-in-Test (BIT) of IMASAT prototype has been defined, including; (PBIT), (CBIT), (IBIT) and HMR.
a NXP T2080 dev kit was delivered to TM, along with the necessary support to configure PikeOS on it.
the acceptance tests procedures of the Computing Node have been defined.
During the 3rd reporting period.
SW and FW developments have been made to cover all the agreed interfaces:RS, ETH, GPIO, CAMBUS , Analog Input, Analog Output, and AFDX .
Improvement of the performance of the equipment, especially in relation to processing speed.
Environmental tests according DO-160 were successfully carried out
An automated testing system was implemented, which greatly reduced the time required for the execution of tests.
Finally, all the defined tests were successfully completed and an updated computer node unit was delivered to the TM.
The main Dissemination channel of the project has been the project website www.imasat.eu.
The consortium also has disseminated project results through their attendance and participation in international conferences and trade fairs, such as OPTRO in Paris, TRANSFIERE in Malaga and ILA in Berlin.
