The Data Compression as a Service (DCaaS) study aimed to bring the benefits of data compression to the experimenters on ESA's OPS-SAT platform. It focused on using the POCKET+ algorithm for the compression of housekeeping telemetry data. The project contained a space component, which performed the compression of provided user data, and a ground component, for the decompression of transmitted user data. Three use cases were selected within the scope of the project: file-to-file, packet-to-packet, and stream-to-stream lossless data transfers.

Future missions are currently being proposed / designed with existing (or moderately inproved) Space-to-Earth communication capabilities in mind. Optical communications technology offers the potential of a dramatic increase in data-rates, specifically in the down-link of science data, thereby allowing for a substantial increase in science return.Direct detection technology using pulse position modulation (PPM) is regarded as the preferred solution for "deep space" optical links.

The Envision CDF exercise has concluded that a bit rate of 75 Mbps is required to comply with the data return strategy, mainly due to big quantity of data produced by the proposed SAR instrument.At the Venus distances the received power on earth is quite limited, requiring a very efficient modulation and coding system.Turbo rate 1/4 is a very efficient coding mode, allowing to go down to Eb/No of 0 to 0.25 dB, which is around 1 dB better than the LDPC 1/2 codes, which is the current solution used in EUCLID at these high data rates.

In applications such as space traffic and disaster response management, there are growing public and private capabilities. Multiple different stakeholders can detect and identify events (space collision predictions, natural disaster definitions). Augmentation of events definitions lead to confusion for local authorities, operators or any users of these information for costly decisions. This project, Space DAO, sets the base infrastructure to agree on consensus mechanisms to reduce confusion and augment trust in key decision making information.

Persistent Responsive Real-Time Earth Observation small satellite constellation mission (PERTEO) was a study dedicated to providing a global democratic service to support disaster management. Earth observation and satellite-based communications play a key role in supporting disaster management targeting responsiveness and the persistence of the service. In the terminology of on-demand Copernicus services, responsiveness is determined by the lead-time and latency. The persistence is determined by the availability and by the revisit time of the service.

'Don't try this at home' (named after one of the AI ships from I.Banks Culture series) is a concept demonstrating the benefits of having a cognitive cloud computing infrastructure in space. Such an infrastructure will provide a comprehensive and scalable set of commercial services to EO sensors and space-based data providers. It enables several applications by efficiently collecting and fusing information on target objects from observations of different platforms at various wavelengths, resolutions, and times. As a result, it leads to timely, precise information.

This project is conceived at analysing a secured communication link between a space-based system and a maritime system. The final goal is to serve autonomous navigation vessels, with a possible extension to other smart commercial maritime services and to favour the process towards a highly and full digitalisation of the Port system. The autonomous ship is here considered from an operating point of view, although quite simple and with the purpose of understanding the impact on the telecommunication system. The initial focus is on three possible telecommunication solutions:
