Could space weather events affect the frequencies of the atomic clocks of GNSS satellites?
To answer this question, INRiM provided a dataset containing the frequencies of the atomic clocks in 17 Galileo satellites from June 2016 to March 2018. The group collected and processed additional data on the earth magnetic field and weather events measured in GOES satellites. These datasets were used to detect and validate geomagnetic storms and identify potential correlations with clocks anomalies.

Additionally, they designed an RNN and trained it on a subset of the dataset provided by INRiM to detect anomalies in the clock frequencies.

The question behind the project work: Use a set of geospatial raster-images and other data collected by Sentinel-1 satellite to create a ML system for the detection of ice presence and concentration in order to automatically produce an ice map. The group explored the concentration of ice using The ASIP sea ice data set of 26 files in NetCDF format.

From that data they extracted matrices and transformed them in order to feed the machine learning model. The trained a U-net model and evaluate the quality of the learning by using the Jaccard coefficient.

Is it possible to automate the identification of the various farming types, using EO images and a CNN Deep Learning model? This is the question they had to answer to ALTEC.

The work path started by processing the EO images coming from Sentinel 1 and 2 satellites (Pre-processing chain already applied by ALTEC). They were then feeded to a FCN U-Net to perform image segmentation in order to classify crops.
