Project description
GNSS-R is a technique to carry out Earth observation based on reflections on the ground (or sea, or ice) of signals originating from GNSS (Global Navigation Satellite System) signals. The proposed project consists of educating a new generation of experts, at doctoral level, able to bring a qualitative leap to this technology. The scientific and technological goal consists of developing such systems based on a synchronized constellation of Cubesats. An important advantage of this arrangement is the very low cost of cubesats and the possibility to increase resolution based on beamforming from the satellites. Ground truth, as well as some of the methods, will originate from near-field radar technology. This will require further research on all segments of GNSS-R technology and beyond: launching and adjustment of cubesat formations, RF synchronization, interferometry between moving platforms, calibration of RF front-ends, ground testing making use of drones, cubesat systems, on-board processing, data transfer and analysis, translation into ground truth and into predictions important for climate change studies and for optimal territory management. The project may also benefit to other technologies making use of interferometry, such as radio-astronomy and phased array based communications. It is also expected to assist industry segments making use of GNSS signals, such as precision agriculture, forestry and sea and land management.

Summary:
New Space and Space 4.0 have been emerging over the last few decades, enabling easier accessiblity to space and the development of new markets, with new opportunities to seize. European companies must already position themselves among the main private actors while developing a sustainable spatial sector embodied in the social and economic structure. Moreover, the Green Deal and European Union recovery plan offer various opportunities to develop space related, environmental-friendly projects. The Walloon Government also identified the space sector as vital in their Regional Policy Declaration in their legislature 2019-2024. Structuring the Walloon driving force in the spatial field requires better coordination between the administrations, universities, and research centers with the industrial sector in order to support research projects within a high-end technological platform. They will consist in meeting advanced technological challenges covering the entire spatial value chain, from manufacturing, instrumentation and launching to post-processing and data services. Particularly, constellations of Smallsats are capable of answering vital societal challenges, such as the monitoring the human global footprint on Earth. Developing disruptive technologies facilitating Earth observation can widen fundamental research perspectives in the framework of sustainable development (climate, agriculture, pollution, etc), and serve direct applications related to global communication and cybersecurity.
Space4Relaunch is a collaborative program revolving around two of the sectors combining high accessibility of the Walloon industrial landscape, and high attractiveness to world space markets. The research promoted by this program will be carried out through a total of 30 PhD theses answering cutting-edge technological challenges towards adequate Technology Level Readiness for industrial needs in the spatial sector.
Space4ReLaunch regroups two researches axes complementing each other for a common roadmap: Win4Space, which is dedicated to Earth observation, and Win4ReLaunch, which focuses on reusable launchers. The Joint Research Institute For Space (JRI4SPACE) has also been created in order to strenghten the synergies between all the actors in the spatial area, and to develop a cross-disciplinary approach for the identified strategic innovation domains.

3DEES - 3D Energetic Electron Spectrometer
Project description
Since 2015 the 3DEES has been developed as a science-class instrument that is optimized for the measurement of angle resolved electron spectra (6 angles) in the energy range 0.1 - 10 MeV in the Earth’s radiation belts. It will be embarked as a technology demonstration on-board PROBA-3. The satellite is scheduled to be launched in 2024 into a highly elliptical orbit and will cover parts of the inner radiation belt, outer belt and mostly the border of the magnetosphere. Thus, the objectives of the 3DEES mission are to give an accurate picture of the high-energy electron population in the magnetosphere for scientific studies of their acceleration and loss processes, through measure of angle resolved energy spectra of electrons, which constitute boundary conditions to advanced physics models. This is one of the rare instruments for this kind of studies that performs in parallel measurements in several looking directions. The mission also targets to deliver Space Weather data for now- and forecasting activities.

EPT- Energetic Particle Telescope
Summary
The EPT is an energetic particle spectrometer that was designed to provide high quality (so-called “science-class”) measurements of energetic protons (9.5 – 248 MeV) and helium particles (38 – 980 MeV) as well as electrons (0.5 – 8 MeV), in the near-Earth environment. After development activities during around 8 years funded by ESA, the EPT was launched on 7 May 2013 on-board PROBA-V into a low earth circular orbit of 820 km altitude. Optimised for light ion detection, EPT provides a good description of their population in the inner radiation belt as well as a good characterization of solar energetic particle events. EPT data also allows studies of the dynamics of the electron radiation belts. It is providing data almost continuously since the launch of the mission and the next year the EPT will have covered a solar cycle (~ 11 years). The PROBA-V/EPT mission is one among few long-lasting missions that provide high quality energetic particles measurements, thanks also to the robustness of the PROBA satellite platform (the first one is still in operation since 2001). Since 2016 the EPT data are part of the ESA Space Weather Service Network wherein they provide various products relevant for space radiation effects assessment.

Short Project description:
In April 2023 started the development of a miniaturized version of the EPT that is in operation on-board PROBA-V since almost 11 years. This version is intended to perform high quality measurements of directional electron (0.1-10 MeV) and proton (3-300 MeV) fluxes in space (science class). The challenge in this project is to develop a light charged particle spectrometer of reduced size i.e. to compact the EPT from an instrument of shoe box size to one of praline box (less than half a liter), but keep the same performance in electron and proton detection in terms of energy range covered.

This project aims at studying the interior of Mars, Mercury, the Moon and natural satellites, and the small bodies of our Solar System by means of geodesy observation and modeling.
Extended project description:
Our investigations focus on the gravity field, the rotation, the tides and the interior structure of these celestial bodies. We contribute to the development of observation strategies of BepiColombo and JUICE, and develop scientific models of the rotation, tides, interior structure and evolution of terrestrial planets and icy satellites in order to improve and refine the interpretation of the upcoming space missions such as BepiColombo and JUICE. We analyze radio science data of the Mars missions InSight in order to study the Martian interior and atmosphere and to prepare for a future LaRa (lander radioscience) mission. We develop interior structure and dynamics models of Mars to improve our understanding of the Martian interior from the interpretation of radio science data. We develop tools and methods to deduce the interior structure of low-gravity objects such as Phobos and the binary asteroid Didymos-Dimorphos, in preparation for the MMX and Hera missions that will soon be visiting them. We complement our studies with data from other geophysical instruments and experiments (e.g. magnetometers, gravimeters).

Summary
The EOSTAT project aims at supporting the uptake of the Sen2Agri and Sen4Stat systems by FAO partner countries in the framework of the establishment of an Earth Observations assisted national crop monitoring system for production of official national agricultural Statistics on crop acreage and yield.
Project description
In line with the Agenda 2030 and the data revolution underpinning the SDG process, FAO is supporting countries in the use of geospatial data and methods as alternative and cost-effective ways to generate data related to the SDG and estimate essential agricultural variables, such as crop acreages and crop yields which can be indirectly measured through Earth Observations and in-situ data.
National Statistical Services frequently face limited resources to collect, analyze and disseminate agricultural statistics on regular basis. Earth Observations, and big data in general, come in the picture as an ideal solution and opportunity for NSOs to fill this gap and strengthen their capacity to timely generate crop statistics at national and subnational level, and feeding this to the SDG indicators. However, Earth Observation data do not come without challenges: they are a special category of Big Data and as such their access, storage, pre-processing and analysis is very demanding and is very much limiting their uptake by countries.
In order to break such technical barriers, FAO established a collaboration with the European Space Agency (ESA) and the Université catholique de Louvain (UCLouvain) as of 2014 to develop open-source user-friendly solutions (starting with the Sen2Agri toolbox, and now with Sen4Stat) to generate national crop maps and estimate yield for the main crops.
The EOSTAT project is supporting the uptake of these tools in 10 partner countries (Angola, Mali, Ethiopia, Rwanda, El Salvador, Senegal, Uganda, Tajikistan, Sri Lanka and Timor Est) in order to better assist NSOs addressing the increasing demand of agricultural statistics and the SDG reporting. Activities combine tools demonstration and capacity building.

Summary
Agroecosystems in Europe need an agroecological transition to ensure sustainable food production, resilience to climate change, biodiversity, and soil restoration. The EU-funded PHENET project will bring together the European Research Infrastructures on plant phenotyping (EMPHASIS), ecosystems experimentation (AnaEE), long-term observation (eLTER), and data management and bioinformatics (ELIXIR) to co-develop new tools and methods for the identification of future-proofed combinations of species, genotypes, and management practices. The project will deliver services enabling access to enlarged sources of in situ phenotypic and environmental data thanks to new AI-based multi-trait and multi sensor devices, unleashed access to high-resolution Earth observation data, FAIR data support, and a new generation of predictive modelling AI and digital twins solutions.
Extended project description
Objectives :
Europe urgently needs to find pathways towards agroecological transition of agroecosystems in support to food security, climate change resilience, biodiversity and soil carbon stocks restoration. In PHENET, the European Research Infrastructures (RI) on plant phenotyping (EMPHASIS), ecosystems experimentation (AnaEE), long-term observation (eLTER) and data management and bioinformatics (ELIXIR) will join their forces to co-develop, with a diversity of innovative companies, new tools and methods - meant to contribute to new RI services - for the identification of future-proofed combinations of species, genotypes and management practices in front of the most likely climatic scenarios across Europe. Ambitioning to go beyond current highly instrumented but often spatially and temporally limited RI installations, PHENET derived services will allow wide access to enlarged sources of in-situ phenotypic and environmental data thanks to (i) new AI-based multi (agroecology-related) traits multi-sensors devices (ii) to unleashed access to high resolution Earth Observation data connected to ground based data, (iii) FAIR data support for connection with (iv) new generation of predictive modeling solutions encompassing AI and digital twins. Developments will be challenged by and implemented in a series of eight Use Cases covering a large range of agroecosystems but also of ecosystems to demonstrate portability of solutions. Several of these Use Cases will mobilize on-farm data. A large effort will be devoted to training RI staff and beyond through a sustained collection of training material fed by experts. Outreaching activities will aim at enlarging the range of RI users. PHENET will not only strengthen RI but will also have major impact on the development of innovative companies on phenotyping, envirotyping and precision agriculture as well as on the emergence of climate smart crop varieties and innovative practices fitted to climate change and agroecological transition.

Summary
The goal of the project is to develop a system for high resolution mapping soil organic carbon (SOC) at the field scale covering the entire Walloon territory. This will require identifying confounding elements to optimize image selection and researching suitable modelling approaches for the Walloon context. Specific challenges are the effect of soil moisture and soil structure on the spectral signal, representing uncertainty in the final maps and the low variability in SOC values in the Loamy soils which cover most of Walloon croplands.

The Sentinel-2 for Agriculture project aimed at providing to the international user community validated algorithms and best practices to produce EO products for agriculture monitoring preparing for the exploitation of Sentinel-2 observations. The project responds and contributes directly to the GEOGLAM initiative.
Extended project description
The Sentinel-2 for Agriculture project developed the open source Sen2Agri system that enables to ingest and process automatically Sentinel-2 and Landsat 8 time series in a seamless way to derive four basic products for agriculture monitoring, identified as a priority by a large user community including the GEOGLAM one: monthly multispectral cloud-free composite, up-to-date cropland mask, mid-season and end-of-season crop type maps, and vegetation status indicator as NDVI and LAI time series. The system was demonstrated in 2016-2017 over three entire countries (Ukraine, Mali, South Africa) and eight local sites distributed across the world. This demonstration allowed very fruitful collaborations with local partners to collect in situ data in a timely manner allowing the production and validation of the Sen2Agri products over all sites. The Sen2Agri system has been uptaken by a large users’ community (more than 2000 system downloads around the world).

Summary
The Sentinels for Common Agricultural Policy project provided the European and national stakeholders of the CAP with validated algorithms, products, workflows and best practices for agriculture monitoring relevant for the management of the CAP. The project paid particular attention to provide evidence how Sentinel-derived information could support the modernization and simplification of the CAP in the post 2020 timeframe.
Extended project description
The Sentinels for Common Agricultural Policy project developed the open-source Sen4CAP system, which is object-based and derives relevant markers and maps from the Sentinel 1 and 2 missions for 8 priority use cases defined in the context of the 2020+ EU Common Agriculture Policy reform: crop type mapping, grassland mowing, EFA practices monitoring, vegetation growing monitoring, tillage detection, parcel heterogeneity detection, bare soil period monitoring and land cover change between years.
The system was validated through full national-scale national demonstration in near real time for 10+ EU countries selected by DG-Agri and JRC. This demonstration was the opportunity to interact closely with Paying Agencies from the pilot countries in order to validate and assess the fitness-to-use of the generated products. Relevant training and capacity building activities were conducted during almost 2 years.
Release of the version 1 of the Sen4CAP system in November 2019. Continuous user support to expand the user community and to make the system evolving according to their needs (with ESA supervision).
The Sen4CAP system was adopted by several countries, as a building block for their own monitoring system. In particular, UCLouvain had the opportunity to train Luxembourg Ministry of Agriculture on Sen4CAP in a specific “LEO4CAP” project, during 2 years.
The Sen4CAP system was also adopted by private companies who build monitoring systems proposed to countries as a service. Sen4CAP is included in the EO-WIDGET portfolio, thanks to the support of the UCLouvain team.

Summary
The Sentinels for Agricultural Statistics project aimed at paving the way for an advanced exploitation of the Sentinel missions to fit the workflow of the National Statistics Office in support of their national reporting and their SDGs international reporting.
Extended project description
The Sentinels for Agricultural Statistics project is developing the open-source Sen4Stat system, which generates a set of Earth Observation agriculture product, using Sentinel 1 and 2 missions, and couples them with the official agricultural surveys to get improved acreage and production estimates. The project is targeting statistics improvement through 6 use cases: cost-efficiency for acreage and production estimates, spatial disaggregation, timeliness, sampling design, survey data quality control and SDG reporting.
The first version of the system has been delivered in 2023. It is being demonstrated through national and regional pilot studies in 5+ countries, in close collaboration with the FAO and World Bank. This demonstration shows the added-value and the necessity to have close interactions with National Statistical Offices to ensure the compatibility and complementarity between their practices and the use of Earth Observation data.
Relevant training and capacity building activities is conducting and planned for the next 18 months. Continuous user support to expand the user community and to make the system evolving according to their needs (with ESA and FAO supervision).

L’idée principale pour fédérer l’énergie et le savoir dans le cadre de Louvain4Space a été de construire un projet de Nanosatellite avec un objectif scientifique in fine mais surtout pédagogique au cours de la réalisation du projet. Thales Alenia Space Charleroi est notre partenaire industriel et l’UCLouvain travaille aussi avec des ingénieurs et scientifiques de l’Observatoire royal de Belgique (ROB) et de l’Institut d’Aéronomie spatiale (BISA).
Le nom du nanosat a été choisi par vote: LUNA pour Louvain University NAnosat.
La première étape a été d’envisager un certain nombre de projets de fin d’étude (master) dans le cadre de notre futur nanosatellite. La liste des sujets de mémoires (ou thèses de doctorat) concerne tous les sous-systèmes d’un nanosatellite ainsi que son instrumentation scientifique et la conception et l’analyse de la mission.
Les sous-systèmes d’un nanosatellite et sa charge utile possible ainsi que les liens vers les promoteurs éventuels sont notés ci-dessous :
Le système de propulsion est l’ensemble des composants qui permettent la mise en orbite du nanosatellite ainsi que son maintien en orbite. Il est constitué de moteurs électriques ou chimiques. Pour obtenir une orbite correcte, il faut prendre en compte les effets de la traînée atmosphérique, des champs magnétiques ou des vents solaires qui dévient le nanosatellite de sa trajectoire. Ces moteurs permettent non seulement la bonne trajectoire, mais également la bonne altitude et la bonne vitesse pour atteindre les objectifs scientifiques.

Des panneaux solaires en combinaison avec des batteries sont utilisés pour fournir une source constante de courant électrique au nanosatellite. Le chargeur des batteries est optimisé pour extraire un maximum de puissance des panneaux solaires. Les batteries qualifiées pour opérer en environnement spatial sont utilisées lorsque le nanosatellite n’est pas en plein soleil, et permettent au nanosatellite de continuer à fonctionner.

Le sous-système de communication utilise des émetteurs, des récepteurs ou des transpondeurs (émetteur et récepteur en un seul système). Il gère l’ensemble des communications vers la Terre. En cas de présence de plusieurs sous-systèmes de communication à bord du même nanosatellite, leur compatibilité électromagnétique doit être soigneusement étudiée.

Le nanosatellite doit survivre aux forces violentes de son lancement dans l'espace. La superstructure du nanosatellite doit également réduire les chocs et les vibrations que des composants internes pourraient subir lors du lancement.
Si le nanosatellite a pour objectif de rentrer dans l’atmosphère et redescendre sur Terre, la superstructure doit être capable de palier au chocs et vibrations associés ainsi qu’à la chaleur due au frottement sur l’atmosphère.

Industrie associée : Aerospacelab.
Le système thermique du nanosatellite doit être capable de réguler la température des composants du nanosatellite car celui-ci subit des variations de températures extrêmes. Les températures oscillent en permanence entre des températures trop chaudes et trop froides pour les composants des instruments et autres sous-systèmes du nanosatellite.

Le nanosatellite doit souvent être orienté en fonction de ses attributions. Par exemple, il doit faire face à la Terre pendant les observations. Un système de contrôle d'attitude permet au nanosatellite de rester correctement orienté. Ce sont souvent des petits moteurs plus faibles que ceux du système de propulsion qui se chargent de l’ajustement d’attitude.

Le nanosatellite doit recevoir les commandes en provenance de la Terre, doit informer la Terre des opérations effectuées et de son état de fonctionnement, que ce soit pendant sa mise en orbite ou lorsqu’il se trouve sur son orbite nominale. Souvent, un simple système « beacon » est utilisé pour permettre à la station au sol de suivre le nanosatellite en orbite. Des informations supplémentaires sont encore relayées au sol, tels que la température de fonctionnement du nanosatellite, l'état de ses programmes et de son système d'exploitation, ainsi qu'une foule d'autres fonctions internes. Le système de communication permet aussi l’envoi vers la Terre des données en provenance des instruments.

Des équipes de recherche/enseignement constituées lors de la Conception et Analyse de Missions étudient les synergies possibles, notamment dans le cadre de l’exploitation des données. Ainsi, deux instruments dont la complémentarité permet d‘atteindre d’avantage les objectifs de la mission en terme d’enseignement et de recherche seraient à privilégier dans le choix de la charge utile. Cela suppose que des plans préliminaires d’exploitation des données aient été élaborés sur base des simulations ou d’expériences au sol afin de démontrer la faisabilité des développements et d’études collaboratives impliquant plusieurs types d’instruments ou de données. Encadrement : Tous UCLouvain + Tous partenaires (à déterminer).
Pour envoyer les commandes et recevoir les données du nanosatellite, il faudra développer un segment sol. Il s’agit d’une station qui envoie et reçoit un signal radio vers le nanosat. Derrière ces envois et réceptions, il faut une organisation qui a beaucoup de visibilité et pourrait être faite par les étudiants.
