NSSDCA ID: DIAPO
This satellite is part of France's contribution to the International Magnetospheric Study. Its objective is to study the origin and acceleration mechanisms of magnetospheric ions (1) by measuring the relative abundances and the angular and energy distribution of singly ionized hydrogen and helium, doubly ionized helium, and oxygen (6 plus) ions and, (2) by comparing the results with the ionospheric and solar wind composition. Additionally, a study of magnetospheric substorms is planned with measurements of the angular and energy distribution of electrons from 50 eV to 1 MeV, complemented with VLF and magnetic field measurements.
