TELETEL designs and develops hardware & software solutions for satellite/spacecraft avionics and ground equipment, with special focus on testing & monitoring tools for on-board data networks, specialized EGSEs, on-board data handling electronics & software, GALILEO interferences & management, etc.
TELETEL is a dynamic company, which is able to adapt fast and fulfill with high quality, specialized industrial requirements. Most of our engineers are currently involved in Space projects and activities, thus having already accumulated significant know-how and expertise with regards to developing & managing space-related programs, technologies and applications.
Since 2007, various activities in the validation of space related components (SpW, SpW-T, SpW-D, IMA TSP, SCOC3, etc.) have been successfully handled, internal infrastructure (i.e. representative testbeds for S/C on-board network architecture) has gradually been built, and TELETEL has developed its own platform/product (i.e. iSAFT) for validation, monitoring and interfaces simulation.
TELETEL has developed and delivered high-quality specialized solutions to leading Space industries including EUROPEAN SPACE AGENCY (ESA), ASTRIUM SAS and is also involved in various R&D programs funded by EU, ESA and industrial consortia.
TELETEL staff have already been working for the past 4 years with ASTRIUM Satellites in Toulouse in respect to the development, integration and validation of on-board software components for the CSO satellites.

SpaceWire-T/SpaceWire-D validation
An ESA/ESTEC project, in which TELETEL has designed and developed a proof-of-concept prototype for the functional and performance validation of SpW-T & SpW-D protocols. TELETEL performed analysis and validation (in terms of latency, efficiency, timeslot periods, etc.) through simulations and prototype implementations on TELETEL’s iSAFT platform, including the RMAP protocol & an RMAP conformance test suite.
SpaceWire Evolutions prototyping/validation
An ESA/ESTEC project, where TELETEL (Prime Contractor) cooperated with ASTRIUM Satellites, 4Links and SCISYS for the definition, design, breadboarding, testing and validation on the iSAFT platform of SpaceWire new features (PnP support, Interrupts distribution, Simplex & Half Duplex), compatible with the current SpaceWire standard. Functional tests performed, validating new features, assessing their efficiency.
FDIR / N-MaSS Instrument Simulator/Analyser
An ESA/ESTEC project, in which TELETEL implements N-MaSS end-point protocols as well as simulation SW of instrument and telemetry / telecommand of data sources, in an instrument simulator / analyser. TELETEL will also perform tests to verify the correct operation of an N-MaSS enabled end node, having as a target to demonstrate the backwards compatibility of N-MaSS to non N-MaSS enabled nodes.
Applicability of ARINC-664 (AFDX) in space on-board data networks
An FP7-SPACE project (MISSION), in which TELETEL designs, develops and validates on the iSAFT platform, a representative ground demonstrator of a S/C on-board architecture, in order to assess the suitability of AFDX technology elements over the SpaceWire physical interface for deterministic on-board data networks.
Starkit/SCOC3 Drivers & System Validation
An ESA/ESTEC project, where TELETEL validated the Basic Support SW for ASTRIUM’s SCOC3 Starter Kit board, consisting mainly of the I/O drivers, and associated Board Support Package. TELETEL has developed in the iSAFT platform the complete Starter kit integrated I/O Test Bench, made of SpW, MIL-STD-1553 and CAN test systems (functional/stress test suites + physical interfaces).
