Innovative Satellite-based PNT concepts for new RAIL Safety of live applications.

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.

Study to implement disaster risk reduction using innovative data exploitation methods and space assets

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.

Antarctic Ice Sounding Experiment using ESA’s P-band Polarimetric Sounder

Space-based radio echo sounding of the continental ice sheets can potentially provide full coverage with uniform sampling and data quality as well as detection of change in environmentally sensitive areas. This research addresses the feasibility of sounding the Antarctic ice sheets with a space-based P-band radar. The assessment makes use of an electromagnetic model of the ice sheets where most of the model parameters are estimated from data that have been acquired in Antarctica with an airborne P-band ice sounding radar.

Integrating SAR interferometry and GNSS for studying tectonic processes in Indonesia

Indonesia is periodically affected by severe volcanic eruptions and earthquakes, which are geologically coupled to the convergence of the Australian tectonic plate beneath the Sunda Plate. SAR interferometry (InSAR) is a satellite technology based on radar sensors that can be used to support the study and modelling of terrain movements such as tectonic motions associated with faults, and volcanic processes related to magma movement. The main advantages of InSAR is the synoptic view of wide areas, and the periodic surveying that guarantees long-term monitoring and time series analysis.

Characterization of the Ionospheric environment at low latitudes, application to Biomass external calibration sites

The Biomass satellite is a polarimetric P-band (435 MHz) synthetic aperture radar (SAR) in a dawn-dusk low-Earth orbit. Its principal objective is to measure biomass content and biomass change in all of Earth’s forests. The mission launch is envisaged around 2024, for a duration of five years.

Investigation of Active Detumbling Solutions for Debris Removal

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.

Use of Earth Observation for sustainable fisheries management in west africa

Ghana and other coastal countries in West Africa are continuously threatened by the adverse effects of IUU fishing in the region. IUU fishing poses an enormous threat to the conservation and management of the dwindling fish stocks, causing multiple adverse consequences for fisheries, coastal and marine ecosystems and for the people who depend on these resources.

Change detection using Interferometric an d Polarimetric signatures in Argentina

This Study comes in support to the CONAE SAOCOM Project. The objective of this project is to accomplish a breakthrough in the development of algorithms and associated tools for change detection in Argentina, the core domain of focus being agriculture. L-band SAR is suitable for monitoring agricultural processes, particularly soil moisture, while at higher frequencies the backscattering of soil is attenuated by vegetation. Several studies also demonstrated that L-band radar signatures contain important information about crop classification and biomass.

M4 Phase A/B1 XIPE PHASE A

XIPE is designed to be launched with a VEGA-C vehicle into an orbit of 550 km and <6° inclination. With this orbit, eclipses last about 35 minutes. Due to remaining spacecraft fragments the mission is planned to end by controlled re-entry. The baseline ground station is Kourou either for S/S or S/X telemetry band, albeit Malindi (or Singapore) is additionally available, if necessary, for additional downloading capability in case of particularly bright sources. The mission duration is 3+2 years.
