[3] PROBA-2 is a small satellite (130 kg) developed under an ESA General Support Technology Program (GSTP) contract by a Belgian consortium led by Verhaert (now QinetiQ Space) of Kruibeke, Belgium.

Two of them are designated to observe the Sun: "The Sun Watcher using APS and Image Processing" (SWAP, an EUV imager) and the "Large Yield Radiometer" (LYRA), a radiometer made of diamond photodiodes.

This institute will also host the PROBA-2 Science Center from which the SWAP and LYRA instruments will be operated and their data distributed.

There are three other instruments to measure basic space plasma properties: the Dual segmented Langmuir probe (DSLP)[1] (developed by the Astronomical Institute and Institute of Atmospheric Physics, Academy of Sciences of the Czech Republic), the Thermal Plasma Measurement Unit (TPMU), and the Science Grade Vector Magnetometer (SGVM) developed by the Technical University of Denmark.
