Plasma diagnostic experiments on board of the Brazilian scientific microsatellite SACI-1 [PDF]

Geofísica Internacional, 2000
A set of three plasma diagnostic experiments, known as PLASMEX, are planned to investigate ionospheric plasma bubbles in the ionospheric region. We propose to measure the density, temperature and spectral distribution of irregularities of plasma using (1)
