FRAME FORMATTER OF OBSERVATION DATA TRANSMITTED FROM OBSERVATION SENSOR IN SATELLITE

摘要

PURPOSE: A frame formatter of observation data transmitted from an observation sensor of a satellite is provided to enable a frame formatter of observation data to multiplex collected data of the observation sensor to use the CCSDS(Consultative Committee for Space Data System) transmission format, thereby reducing a hardware number, weight and power of the satellite. CONSTITUTION: A data transmitting unit(101) includes an intrinsic sync word in observation data. Data obtaining units(105-1,105-2) obtain the observation data by detecting the sync word inside the observation data. Packetizing units(106-1,160-2) generate packet data by insertion of an intrinsic packet head for the observation data. A multiplexing/frame generator(104) determines the size of a memory. A multiplexing/frame generator generates multiplexed frame data.
