NSSDCA/COSPAR ID: 1972-094A
This spacecraft was a follow-on to Intercosmos 2, but was intended for higher latitudes. It was designed to obtain data on: (1) the concentration of electrons and positive ions in the immediate vicinity of the spacecraft while in orbit; (2) the electron temperature and the total electron column concentration (between the satellite and the earth's surface) at various points in flight; and, (3) particle streams of electrons with energies >40 KeV and protons with energies >1 MeV. The spacecraft contained a Bulgarian-made ion trap as well as sensing and measuring equipment made in East Germany and Czechoslovakia. The majority of on-board equipment was Soviet.
