AEROS satellites were to study the aeronomy i. e. the science of the upper atmosphere and ionosphere, in particular the F region under the strong influence of solar extreme ultraviolet radiation. To this end the spectrum of this radiation was recorded aboard by one instrument (of type Hinteregger) on the one hand and a set of 4 other instruments measuring the most important neutral uand iononized parameters at the satellite's position on the other.
Aeros was built by Ball Aerospace for a co-operative project between NASA and the Bundesministerium für Foschung und Technologie (BMwF), Federal Republic of Germany.
Named for the Greek god of the air at the suggestion of the BMwF .
AEROS A and B carried identical instrumentation only the instrument measuring short scale varaiations of the electron density didn't work on A. A third Aeros C was planned for Earth Resources studies in a 3-axis spin-stabilized configuration, to be launched by a Shuttle in 1986.(Needs research)
