CCSDS PACKET TELECOMMAND ENCODERToutain, Philippe; SCHLUMBERGER Industries (International Foundation for Telemetering, 1992-10)The European Space Agency (ESA) decided in March, 1991 to phase out the existing telecommand standard (PSS-45) and replaces it with the new CCSDS (Consultative Committee for Space Data Systems) compatible standard, the packet telecommand standard PSS-04-107. SCHLUMBERGER Industries has developed a telecommand encoder, the TC 3900, which complies with the packet telecommand standards. It belongs to a new family of modular products using new technologies and incorporates in only one single housing of 7 units high and 19" wide, the telecommand encoder, a PSKFSK sub-carrier modem, and WAN (Wide Area Network) and LAN (Local) interfaces. The CCSDS recommendations oblige to implement new functions, which were not used with previous standards : we propose to describe what are the new services provided by the packet telecommanding and how they have been implemented in the TC 3900 encoder.
IMPLEMENTATION OF CE83 FORMAT IN A GROUND-BASED TELEMETRY SYSTEMDaniau, Marc; Millet, Philippe; SCHLUMBERGER Industries (International Foundation for Telemetering, 1992-10)DELTA 6000 System is a universal opened system for preprocessing, archival, realtime and offline analysis of telemetry data. The heterogeneous LAN architecture of DELTA 6000 comprises several front end ensuring the telemetry and high level realtime processing functions and several workstations for system control and display. The high communication level of DELTA 6000 enables an easy resource sharing as well as integration in customer environment. Easy operation through an efficient human interface and high versatility through the largest use of the most famous hardware and software industry standards are the major features of DELTA 6000. The more recent evolution of DELTA 6000 is the CE83 format realtime handling for use in European missiles programs.
