The method we present is developed as part of an onboard satellite images compression with target ratios greater than 6. Such a compression is required because of the weight and memory constraints of on-board equipment and must be integrated in a bit rate control scheme. In order to guarantee a high local quality on some critical areas, we have developed an adapted encoder which integrates a local...
As part of an ongoing effort in the area of space mission security, the Consultative Committee of Space Data Systems (CCSDS) created a working group to develop a Security protocol at the Data Link layer for Telecommand and Telemetry communications. While ad-hoc security implementations have been developed by several CCSDS Member Agencies, there is a recognition that a commonly engineered security...
Two standardization bodies are currently actively working in the field of space links communication protocols: CCSDS and DVB. These two bodies have developed and specified a series of channel coding and modulation techniques which specifically address the specificities and constraints of space links. Nevertheless, CCSDS and DVB standards differ in many instances because they try to answer different...
