High-flying Proba-3 will survey Earth’s radiation belts

The Proba-3 mission is set to demonstrate technologies needed for highly precise satellite formation flying, while also mapping the radiation content of the space through which it moves. The mission’s 3D Energetic Electron Spectrometer will measure electron fluxes as it passes through Earth’s radiation belts.

“Since we know in advance what the satellite’s orbit will be, we know what its position will be at any given time. Based on this information we can write automatic commands that are uploaded to the satellite, so that the instrument does not need active oversight.”

Although different in layout and operation mode, the instrument’s technology builds on that of its predecessor, the Energetic Particle Telescope (EPT), flying aboard the Proba-V mission since its launch in 2013. More than a decade on, EPT is still collecting data and contributing to ESA’s Space Weather Service Network.
