CCSDS PACKET TELECOMMAND ENCODER

International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, CaliforniaThe 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.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
