“…It is important to cover the whole end-to-end path when creating reliable, secure communications. Cybersecurity issues have recently been studied from different viewpoints including general issues in space networks [169], integrated satellite-terrestrial systems, [170], 5G and beyond networks [171], looking at the effects of machine learning on security [172], and ensuring secure telemetry and command links [173].…”

During the New Space era small countries are becoming important players in the space business. While space activities are rapidly increasing globally, it is important to make operations in a sustainable and safe way in order to preserve satellite services for future generations. Unfortunately, the sustainability aspect has been largely overlooked in the existing surveys on space technologies. As a result, in this survey paper, we discuss the multi-layer networking approaches in the 6G era specifically from the sustainability perspective. Moreover, our comprehensive survey includes aspects of some interesting industrial, proprietary, and standardization views. We review the most important regulations and international guidelines and revisit a three-dimensional architecture vision to support the sustainability target for a variety of application areas. We then classify and discuss space safety paradigms that are important sustainability enablers of future satellite communications. These include space traffic management, debris detection, environmental impacts, spectrum sharing, and cyber security aspects. The paper also discusses advances towards a planned European connectivity constellation that could become a third flagship infrastructure along with the Galileo and Copernicus systems. Finally, we define potential research directions into the 2030s.INDEX TERMS Aerospace engineering, Low earth orbit satellites, Radio spectrum management, Spaceborne radar

“…Evolving space systems should include methods to encrypt communication data optimally utilising AES and IDEA algorithms to meet the requirements of data critical teleoperated applications, while considering the authenticity of the data using suitable hash algorithms (Saha et al, 2019). In addition, updated communication protocols and data packet structures are necessary to meet the security requirements for novel applications (Saha et al, 2019). Moreover, such complex characteristics must be supplemented by redundant systems to provide resilience in the event of a component failure (Saha et al, 2019).…”

“…These data are usually composed of values periodically registered by different types of sensors, including temperature, pressure, attitude, and orbit control measurements [1]. Reliable and timely reception of these data is paramount to guarantee nominal system behavior, as well as its safety and that of surrounding spacecraft [2].…”

“…Algorithms that produce smaller coded data volumes are more advantageous in terms of bandwidth usage, transmission latency, and operational costs. Notwithstanding, compression must comply with the computational and energetic constraints imposed by the mission [2], [3], [5]. Lossless compression is also considered a requirement in many remote sensing mission types [6]- [8].…”

The Consultative Committee for Space Data Systems (CCSDS) recently published a lossless compression standard for housekeeping and telemetry. These data are critical for the safe and productive operation of virtually all remote sensing missions, including Earth observation. The new standard, CCSDS 124.0-B-1 "Robust Compression of Fixed-Length Housekeeping Data," allows lossless, real-time telemetry packet transmission with low energy and memory requirements. Furthermore, it offers flexible resiliency mechanisms to resume decompression after losing one or more data packets. This work provides an accessible introduction to CCSDS 124.0-B-1, paying special attention to its resiliency features. Two novel and complementary decoder resynchronization strategies are also presented, which maximize the amount of correctly decoded data. Comprehensive experiments with real and simulated mission data were conducted for this work to assess the standard's performance and the impact of user-defined parameters. Results indicate competitive coding performance, with average compression ratios between 4 and 16 depending on the dataset. Smooth trade-offs are also observed between compression performance and the degree of protection against data loss events, which enhances the usability of CCSDS 124.0-B-1 in multiple mission types and operational conditions.INDEX TERMS CCSDS 124.0-B-1, data compression, telemetry.
