Measure the ionosphere and reconstruct ionospheric electron density profile using radio occultation technique.

Measure the ionosphere and reconstruct ionospheric electron density profile using radio occultation technique. The nanosatellite should measure the flux and spectrum of electrons of 1-20 MeV gamma anomaly in the South Atlantic and polar cusps. It could also save the gamma flux from the Sun, visible on a low orbit.

These data will be useful to better understand the Earth's ionosphere, its relationship with solar activity and space weather. The nanosatelite contains two payloads: a dual frequency GPS receiver and a gamma ray scintillator.
