Satellite Data Formatting and Packetization
Satellite instruments generate scientific data and associated engineering, housekeeping, and other metadata aboard spacecraft. This data needs to be transmitted reliably and transparently to users located in space or on Earth, which creates a need to format, parse into packets, and transmit space-acquired data from source to user in a standardized and highly automated manner. The Consultative Committee for Space Data Systems (CCSDS) is an international organization formed by the space agencies of the world to recommend and develop international standards for spacecraft data and information systems. As a subcommittee of the International Organization of Standards (ISO), the CCSDS has developed international standards for the transmission of space-acquired data from source to users to ease the transition toward greater automation within individual space agencies and to ensure harmony among the agencies, thereby resulting in greater cooperative opportunities and services.
