Our team and mission

The Copernicus Hyperspectral Imaging Mission for the Environment (CHIME) aims at augmenting the Copernicus space component with precise spectroscopic measurements to derive quantitative surface characteristics supporting the monitoring, implementation and improvement of a range of policies in the domain of raw materials, agriculture, soils, food security, biodiversity, environmental degradation and hazards, inland and coastal waters, snow, forestry and the urban environment. For this CHIME is currently developed which will allow collecting a large amount of data with high spatial, temporal and spectral resolution. In order to handle the data volumes, CHIME is playing a pathfinder role for On-board data processing bridging the gap between latest state-of-the-art research, newest Earth Observation Applications and On-board processing technology development. In this context Artificial Intelligence (AI) allows automatic retrieval/analysis of the hyperspectral Earth observation imagery from the satellite’s sensor on-board, amongst others for pre-filtering of Earth observation data so that only relevant parts of the image with usable information are downlinked to the ground. This would allow improving bandwidth utilisation and significantly reducing aggregated downlink costs. Further, AI and related machine learning will improve the retrieval accuracy of geo-biophysical variables from the hyperspectral data-sets.

Recently, the first artificial intelligence (AI) technology carried onboard a European Earth observation mission, ɸ-sat-1, launched from Europe’s spaceport in French Guiana provided an enhancement of the Federated Satellite Systems mission (FSSCat). This pioneering artificial intelligence technology is the first experiment to improve the efficiency of sending vast quantities of data back to Earth, using on-board AI techniques.  


The purpose of this Research Fellowship is to investigate potential AI approaches to support higher-accuracy geo-bio-physical variable retrieval from massive CHIME data sets. Further the pre-filtering of relevant (e.g. cloud-) contaminated data onboard the satellite after data acquisition for transmission down to ground depending on Ground targets needs is to be analyzed and tested.


Field(s) of activities/research/learning areas

You will work in the framework of Onboard data processing (AI) helping us to bridge the gap between latest state-of-the-art research, newest Earth Observation Applications and currently ongoing CHIME on-board processing technology development.

Depending on your previous research experience you are invited to suggested topics in the following areas:

  •  Developing new algorithms for onboard (on-ground) AI implementation depending on processing architectures (inline and/or offline);
  • Implementing and testing new algorithms or scenarios with existing CHIME End-to-End simulator;
  • Testing AI-based selective data reduction and compression schemes, e.g., for latency and frame loss;
  • Implementing CCSDS 123.0-B-2 (lossless and near lossless) or optimized forms of the standard;
  • Developing and testing novel algorithms for hyperspectral image processing for geo-bio-physical variables extraction, e.g., for Feature / Information Extraction or Super resolution.

In particular, your activities will be to:

  • Proposing and performing research in one of the above themes, bringing the power of novel on-board processing technologies and AI-based algorithms to Earth Observation;
  • Publishing results in peer-reviewed publications;
  • Sharing your research within conference and workshops, as well as using modern communication tools (webinars, Jupiter Notebooks, social media).
