This study aimed to achieve the following objectives:
-
To anticipate the security needs and requirements of future space missions (Earth observation, communication, navigation, science, exploration, etc.) with respect to architectures considered for future missions.
-
To build an advanced security architecture portfolio embedding state-of-the-art security concepts, technics, technologies, components and solutions.
Thales Alenia Space
The VHF Data Exchange System (VDES) is a future maritime communication system with the principal objective of enhancing maritime communication applications, based on robust and efficient digital transmission with wider bandwidth than Automatic Identification System (AIS), with a data rate up to 32 times the current AIS. As for AIS, VDES is mainly a ship-to-ship and ship-to-shore system. The ship-to-shore system will use the terrestrial VDES infrastructure that will extend the VDES coverage to only around 60 km from the shore.

Optical satellite communications play an increasingly important role in a number of space applications. However, if the system concept includes optical links to the surface of Earth, the limited availability due to clouds and other atmospheric impacts need to be considered to give a reliable estimate of the system performance. An OGS network is required for increasing the availability to acceptable figures.

In summary, this activity used simulated and analysed parameters for each component to define the requirements for each application. For the flight model, the most important parameters are power consumption, cost and mass of the components. The power consumption and mass of components are acquired from the datasheets. Since space qualification is needed for these components the cost estimation is a difficult task. For example, even for the passive component the price difference between non-qualified, qualifiable and qualified devices is rather high.

The DTN-EO study was initiated in order to research the performance of DTN in future missions, particularly Earth observation and constellation-type missions. In the original proposal, ESA stipulated three scenarios which were to be tested: Earth observation, constellation, and exploration missions. These scenarios built upon each other, starting with an Earth observation-centric mission such as the Sentinel missions, before moving to a large constellation. Ultimately, the DTN network from the first two scenarios was expanded to represent a deep-space exploration mission.

The purpose of this study was to define the a communication subsystem architecture (including both ground and space segments, as well as operational methods) that allows robust RF TT&C links during superior solar conjunction phases. The defined architecture shall ensure robust and reliable links in scintillation regimes (i.e. at low SEP angles) where TT&C links are nowadays degraded, leading to occasional link interruptions. Similarly, the defined architecture shall ensure that at even higher scintillation regimes (i.e.

The study aims at investigating technical solutions to design a reliable TT&C system during superior solar conjunctions, to mitigate the detrimental effects of phase and amplitude scintillation, which limit the maneuvers under 5 deg of Sun- Earth-Probe (SEP) angle. After the analysis of data acquired during superior solar conjunctions of Mars Express (MEX) in 2013-2015 and Cassini in 2001-2002, that allowed deriving a mathematical model to be used in the simulations, the current ESA TT&C system has been evaluated, in terms of link performance.

While the MEOSAR is moving to FOC with Galileo satellites that are equipped with SAR transparent payloads, ESA is already investigating its future Galileo-2 (G2G) system for new features. In this framework, one of the aims of the ESA study on Future Concepts for Galileo Search And Rescue was to define a preliminary design of a new SAR payload capable of processing both First Generation Beacon (FGB) and future Second Generation Beacon (SGB) signals.

MEOSAR is a system designed to locate emergency beacons anywhere on the Earth in order to coordinate rescue efforts for people, vehicles and facilities in distress. It works by evaluating the time and the frequency of the beacon signal upon arrival at the receiver. From these the relative distance and velocity of the sender can be calculated if sufficient data points have been collected. It is beneficial to receive the beacon on several different spacecraft to optimise the accuracy of the trace.
OHB System AG
The main objectives of this study were: to appraise existing ESTRACK groundstation receiver anddemodulator equipment; to demonstrate the feasibility of introducing DSP technology up to the 70 MHz I/F interface for next generation receivers; to identify and propose a design architecture;to identify functional modules common to different demodulation types; and to identify criticaltechnical areas that required breadboarding in Phase 2.
