In a period of just a couple of years the Ångström Space Technology Centre (ÅSTC) – at that time a university division – span off four joint stock companies.

Rotundus AB was built around the idea of using a spherical rover robot, initially intended for planetary ground exploration, in the surveillance business.

NanoSpace AB has the overall mission of exploiting microsystems technology in space, but is currently specializing in propulsion systems based on heated cold gas.

The Ångström Aerospace Corporation AB (ÅAC) commercializes on a wider range of results from the ÅSTC, and has, for instance, made significant progress in miniaturizing multichip electronics.

Kalogi AB, finally, is actually one of the founders of ÅAC, and can be regarded a more general developer and provider of solutions based on microsystems technology.
