Implementation of the European Train Control System (ETCS) Level 2 requires that a huge amount of physical balises (known as Eurobalises), used to determine each train’s position and direction of motion, be deployed in order to support safe operation of high-speed/high-frequency train services all along the European railway infrastructure. The associated costs are substantial, which motivates the investigation of cheaper technologies.

The inexorable progress made in the past years in the field of Earth observation (EO) technologies offers a huge potential for innovation in Disaster Risk Reduction (DRR) applications. Interferometry processing of SAR data is one of the standard techniques for the detection, detailed characterisation and monitoring of surface motion caused by natural disasters. Yet the transfer of this technology progress to the user community needs to move forward in order to ensure that advancements in satellite technologies are transformed into services to be used by the community.

The main objective of this study 'DETUMBLING – Investigation of Active Detumbling Solutions for Debris Removal' was to propose and investigate a contact-based de-tumbling strategy using a robotic arm. Realistic models were developed for the chaser with robotic-arm, target and composite systems. Specific GNC strategies were developed for the different phases of the mission: robotic-arm deployment synchronisation with the target de-tumbling the composite.

The objective of this document is the presentation of the final synthesis of the activity “HIPNOS”, Development of a representative HW/SW solution for a high-performance processing platform for Active Debris Removal missions. Implement COTS-based solution as Demonstration of the activity.
HIPNOS includes trade-off study of processing technologies, processing space-grade and COTS devices, processing architectures, trade-off for computer vision algorithms, and demonstrator of the selected solution.
The scope and objectives of the activity are:

The objective of ESA PREGO activity (ESA/ESOC contract 4000115173/15/F/MOS) is to improve the capacities on re-entry prediction thanks to a complete analysis of the outstanding data set related to the GOCE re-entry occurred in October/November 2013.

The main goal of GEROS-ISS is to demonstrate the capabilities of GNSS remote sensing to derive geophysical parameters of ocean, ice and land surfaces, which are associated with geophysical research with special focus on relevant climate change phenomena.

The SAVOIR/SAG identified the modular RTU as a high priority building block. This is one of the key avionics building blocks as the provided functionality is required by the majority of ESA missions.

An EQM has been developed and validated. FR in June/July 2017. EQM Test completed!. The EQM will be used as EM of the Proba3 IEU and it has been used to qualify the design of the IEU of Proba3. EQM campaign concluded and the unit is to be delivered to Proba3.

The population of non-operational objects in the space environment is raising, increasing concern about the safety of operations for current and future space activities. In this respect, space agencies and in particular ESA with its ESA/ADMIN/IPOL (2014) have established policies to mitigate space debris creation. Please refer to the compendium of space debris mitigation standards adopted by states and international organizations, [RD.5], for additional information. This basically implies that satellites in LEO and GEO shall perform an End Of Life (EOL) disposal with a reliability of 90%.
