CCSDS Protocol Stack for Future High Data Rate Space Missions
The upcoming data science and EO missions will be requiring unprecedented high data rates in order to provide customers with large volume of data on daily basis. As such, a proper ground segment infrastructure tailored to such needs as well as sophisticated space segments are envisioned to meet these performance targets. More importantly, the overall system design has to be supported by proper communications protocols, from the physical layer up to the application. In this respect, the Consultative Committee for Space Data Systems (CCSDS), serving as standardization body for space missions, has been developing a rich framework to support the different phases of a mission and more interestingly has been developing a large portfolio of communication protocols that applicable to high-data rate missions. Starting from this baseline, this seminar will discuss the main communication protocol supporting telecommand and telemetry at the lower layers of the protocol stack, as well as elaborating further on the communications means to support more complex missions, where multiple interconnected space assets are present. As such, the seminar will also provide details about the opportunities offered by the Delay Tolerant Network (DTN) architecture and its interface with the lower layers of the protocol stack as well as its interworking with the applications in use for support the future space missions (such as CFDP and PUS protocols, just to cite a few of them).
