automatic detection of abnormal behaviour || ActInSpace Challenges


Suggest a design for your connected object that is as user-friendly as possible
Design an application to clearly identify abnormal behaviour (graphs, warnings, etc.)
Draw up a business plan for your system
Collect data and anticipate situations, even the unexpected!
Make a video illustrating how the algorithm contributes to your system
Automatic detection of abnormal behaviour


Satellites need to be tracked by a ground control centre that collects and monitors the data for the different parameters recorded on board.Until now, only values outside their expected operating range were detected. CNES has recently developed algorithms for automatic detection of abnormalities (WO2017098030), even when the values remain within the nominal operating range, based on a process for learning the nominal behaviour of the satellite by analysing telemetry data recorded since the beginning of the satellite’s life. As well as reducing the calculation time for the detection of abnormalities, this innovative patented method enables the module to anticipate previously unidentified and unpredictable problems during orbit, on the fly (abnormal decrease of battery load, unexpected heating of a piece of equipment, etc.).


Your challenge is to find an application in a non-space-related field, such as medicine, that could improve and facilitate the monitoring of health in everyday life (unsupervised detection, i.e. without knowing a priori the type of abnormality to detect, for example concerning heartbeat, diabetes, temperature, etc.).

Connected objects are becoming increasingly powerful and with the right sensors could be used to create a database that, after a certain time, would be large enough to detect unexpected changes in the health of an individual (new events, abnormalities).
You will also need to design an attractive software interface (application) and design a connected object that could be used. Anyone should be able to use the system easily. Provide a drawing of your design, capable of convincing an investor.

To respond to this challenge, base your approach on the simplified market study provided by CNES.
