EGSE for the MicroCarb Instrument (Customer: ADS France)

TELETEL has delivered to Airbus Defense & Space Toulouse two (2) EGSEs for the MicroCarb Instrument. The MicroCarb Instrument EGSE consists of the EGSE Front End Equipment (EGSE-FE) provided by TELETEL and the EGSE CCS and QLK software provided by TERMA. The EGSE FE is based on the iSAFT SpaceWire Simulator product, plus COTS components for the Power and I/O Front Ends and custom HW/SW developments.


EGSE Microcarb
EGSE for the EUCLID Antenna Deployment and Pointing Mechanism Electronics (ADPME) (Customer: SYDERAL, TAS-E)

TELETEL has delivered to Syderal (Switzerland) and Thales Alenia Space Espagna the EGSEs for the EUCLID Antenna Deployment and Pointing Mechanism Electronics (ADPME). The ADPME EGSE DFE is based on the iSAFT MIL-STD-1553 Simulator product. The ADPME EGSE Power and I/O Front Ends is realised by COTS components and custom HW and SW developments.


EUCLID Application Software development (Customer: SPACEBEL, TAS-I)

TELETEL develops the EUCLID Application Software components including Thermal Control, Power management, Payload management, TT&C management, CMDS management, System safeguard logic.


JUICE CFDP On-board Software Development (Customer: ADS France)

TELETEL designs and develops the on-board CFDP protocol for the JUICE mission.


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.


A new network paradigm for the On-Board Reference Architecture

An ESA/ESTEC project aiming to specify, design and prototype a new network paradigm fulfilling the needs of the distributed On-Board Software Reference Architecture (OSRA). TELETEL extended and used its iSAFT SpaceWire Simulator as Front End Equipment to emulate one or multiple End Systems connected via SpaceWire links to a LEON board and implementing the OSRA network communication concepts.


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.
