CCSDS stands for Consultative Committee for Space Data Systems. Founded in 1982 by the major space agencies, the CCSDS maintains communication standards for spaceflight. Today this forum consists of 11 space agencies and leading experts from 27 nations.
Communication standards published by CCSDS were by more than 900 space missions launched over the span of almost three decades. The main goal is to promote the interoperability of space systems and ground networks to enable new capabilities for future missions.
CCSDS has defined the structure and major standards of the communication protocols commonly used in the space missions all over the world. A subset of those standards has been implemented in PUSopen® to form easy-to-use comprehensive space communication middleware for small satellites.
Selected CCSDS standards allow to wrap customer-defined data into packets and frames and allow for synchronization of the data units in the transmitted byte stream. In the terminology of the ISO/OSI model, the PUSopen® implements the following transport layer and link layer standards: Space Packet Protocol, Unified space Data Link Protocol, and parts of TM/TC Synchronization and Channel Coding standards.
