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).
Protocol Validation System (PVS) for on-board communications
An ESA/ESTEC project, where TELETEL is developing an open, generic & fully integrated tool for validation / conformance testing, protocol monitoring & analysis, traffic generation & fault injection, and interfaces simulation supporting multiple physical interfaces (SpaceWire, ECSS 1553, ECSS CAN) & various on-board communication protocols (RMAP, PTP, Space Packet, TM/TC, CANopen, etc.), based on specific Space Industry needs and constraints.
Application of a BitTorrent-like data distribution model to Mission Operations
An ESA project with Thales Alenia Space France and INRIA in which design and simulation activities were performed with respect to the use of a torrent-like distribution model for space-ground and ground-ground communications in a high performance satellite scenario and a QB50 constellation scenario.
