The Royal Observatory of Belgium (ROB) has the scientific responsibility for
Proba-2's two solar monitoring instruments, the Sun-imaging SWAP (Sun Watcher
using APS detectors and imaging processing) instrument (which makes detailed
images of the solar atmosphere once a minute,) and the the LYRA (Lyman alpha
radiometer) instrument.
Proba-2 combines solar observation with plasma content monitoring of the space
around it, revealing how the Sun's activity can influence Earth's ionosphere.
The satellite carries two instruments, the Dual Segmented Langmuir Probe (DSLP)
and the Thermal Plasma Measurement Unit (TPMU). Both were developed by a
consortium of Czech institutions led by the Czech Republic's Academy of
Sciences with considerable support from the Czech Space Research Centre.
Carries an experimental propulsion system which is refuelled with gas generated
from a solid material. It produces 250 times its own volume in pure nitrogen
gas.
