SpaceWire and SpaceFibre Network Study

An ESA/ESTEC project in the field of SpaceWire / SpaceFibre on-board data networks, aiming to specify and breadboard a SpaceWire and SpaceFibre network routing function and to verify its quality of service at network level. TELETEL extended and used its iSAFT SpaceWire Simulator and its iSAFT SpaceFibre Simulator to connect (through both SpaceWire and SpaceFibre links), configure and validate the SpW-SpFi bridge, through a set of representative validation scenarios.

IMA Separation Kernel Qualification Campaign

The main purpose of this ESA GSTP activity is the qualification of XtratuM hypervisor (SW criticality Cat. B). TELETEL is developing a validation platform and the relevant test suite for the qualification of XtratuM using TSIM for LEON3 simulator and the GR712RC development board. The activity is supervised by CNES as well.

EGSE for the SIROM Interface and Command & Control application for Space Robotics testbeds

An H2020 project with SENER, AIRBUS DEFENCE & SPACE, THALES ALENIA SPACE, LEONARDO and other industrial and research partners in the field of robotic handling of payloads in future space missions. SIROM realized a set of integrated and inherently optimised interfaces for mechanical, data, electrical and thermal connectivity that allow reliable, robust and multi-functional coupling of payload to robot manipulators or payload to other payload. TELETEL provided the EGSE for the validation of functional, performance and reliability requirements for the Data and Electrical I/Fs, based on its iSAFT Product Line and specifically the iSAFT Simulator and iSAFT Recorder instances. Additionally, TELETEL provided command and control application SW for a representative ground testbed for robotic handling of payloads in future space missions.
