The International Space System Engineering conference was celebrated this year in Warsaw from June, 3rd to 5th.This yearly event aims at presenting the research and innovation projects carried out by the main stakeholders of the european space industry and thus, presents a good opportunity for opening face to face discussions about the technological trends for the coming programs.Within the presented topics we can highlight:• Operating systems for multi core architectures : the processing power needs are increasing on the near future space programs and the architectures of the currently qualified operating systems are still not ready to ensure a robust and deterministic execution of the Spacecraft control SW.• Time prediction within multicore architectures: An extension of the previous topic more focused on the time partitioning and determinism issues.• CCSDS file transfer protocols: Euclid mission needs the transmission of large quantity of data through noisy, bandwidth-limited, asymmetrical, and interrupted communications links with very long propagation delay. The CCSDS File Delivery Protocol, usually used in NASA missions, is a good candidate under study. Some demonstrators are presented.• New components in the SAVOIR HW reference architecture: flash memories or SATA controllers become the next HW candidates to get integrated into spacecraft data handling systems.• Spacefiber implementations (Spacewire over fiber): presentation of a spacefiber network as well as the related test results.• The trends on avionics deterministic networks (AFDX versus TTETHERNET): S/C architectures based on 1553 require a huge effort of network configuration to ensure the increasing number of network nodes and data budgets. With the aim of replacing the old Milbus, some standards are currently under assessment.GTD participation was focused on this last topic, on which, as co-writers of one of the presented abstracts, we strongly recommend the use of AFDX (Avionics Full DupleX switched Ethernet) to ensure the functions at Data Link layer on the future spacecraft architectures. This standard is widely used in Civilian Aeronautics and has demonstrated to be deterministic, robust and suitable for modular architectures. Spacewire and Ethernet are, respectively, the two standards selected to supply the physical layer for this assessment. GTD collaboration with Airbus DS in this topic, includes the development of a configuration tool for AFDX network.
