The development and testing of a prototype of an analog IF over digital IF acquisition/generation demonstrator for instantaneous signal bandwidth up to 5GHz, together with a set of data compression techniques to minimize the digital data rate required to transmit a given analog IF bandwidth over a terrestrial network, optimized for a selected couple of scenarios.
In this program, two replacement subunits of the LCT were developed and qualified. The units are the Fame Unit Structure (FUS) and the Telescope Unit (TLU). These units replace previous units and have to comply with the existing LCT design. This development took into account experience gained from the previous designs and handling to achieve a robust design and decrease overall cost of LCT while maintaining the known performance requirements.
TLU and FUS have significant influence on the LCT mechanical design. Therefore, a LCT mechanical demonstrator (LMD) was built to qualify the required mechanical loads.
The project MLSAT investigates the applicability of machine learning or in general, artificial intelligence techniques in the context of satellite communications.

Since satellite operators aim for more bandwidth to increase data throughput and capacity new system and payload concepts are required, leading also to the demand for new equipment. One promising option to increase capacity for HTS systems is moving the feeder link from Ka-band to Q/V-band. The focus of this activity targets the development of Q-band linearisers.
On-board handling of higher-layer protocols via an ad-hoc router device makes it possible to provide satellite connectivity completely by-passing the (possibly) clogged/compromised terrestrial infrastructure, to facilitate IP mobility, to reduce traffic load on satellite uplinks by deploying IP multicasting on board the satellite, and to provide true packet-by-packet end-to-end connectivity between satellite terminals in meshed configuration or ISL environment.
Low-Earth-orbit (LEO) satellites are flying in an altitude between 200km and 2000km above Earth and hence are limited in the amount of time they are visible to a ground station (typically around 20 minutes). This is limiting the amount of data that can be exchanged. However if the data is relayed to a geosynchronous-Earth-orbit (GEO) satellite, the available LEO satellite data transmission time (and amount of data) can be drastically increased.
This project covers the design and the development of the link and network layer mechanisms required to support end-to-end unicast data connectivity over inter-satellite links in small satellite constellation networks. SPIDER stands for Small Platform Inter-satellite Data Exchange Routes, being an obvious reference to the spider’s ability to create webs, which is precisely the purpose of this project.

In HENCSAT we have developed a novel concept based on bit-torrent and network coding technologies that provides more resilient networking that can be loaded closer to its full capacity.
HENCSAT empowered the study and testing of robust and powerful networking over heterogeneous satellite and radio links in potentially difficult mobile scenarios where packet loss and interruptions may occur. By applying Network Coding in combination with novel resource management significant improvements can be obtained over traditional approaches. Application areas include aerial, vehicular and maritime users with sources like photos, video and other critical data. The focus was specifically on video over multiple networks.
The project consists in advanced activities paving the way to NewSpace equipment, intended to cover the platform needs in terms of electronics. The key success factors are a drastic reduction of recurrent price and mass of the equipment based on three pillars : integration & standardization, low cost components and innovative technologies.
The mission of RHEA Cyber Security Centre of Excellence is to develop supporting technologies enabling agile and effective cyber-security services, including education and training, operations, research, experimentation, test & evaluation, supporting the needs of the European space community as well as the wider aerospace, humanitarian, critical infrastructure, and defence & security communities.
Thales Alenia Space is a major player in the LEO, MEO, HEO GEO, L2 or interplanetary satellite industry and has therefore a large background in systems and subsystems definition.
In particular, Thales Alenia Space is developing a new product line of geostationary telecommunication satellites, Spacebus NEO, more and more powerful where harness accommodation is already challenging.
The study of a new harness architecture based on a large flexible printed circuit board, associated connectors, intelligent connectors integrating multiplexing and demultiplexing functions will ease the harness accommodation for telecommunications payloads.

QUIC is a new encrypted-by-default Internet transport protocol that accelerates HTTP traffic and which has the intention to eventually replace TCP. The project objectives are to identify the root causes of any shortfalls in QUIC performance over satellite, influence and propose changes to the specification, and evaluate them using a real-time emulation test bed. The results of this work are contributed to the IETF.
The M2M market is increasing fast and more bandwidth is required. Ku-band M2M services can offer this bandwidth but require low-cost front-end components to be accepted by the market.
