Tested in Space

Sensonor has been selected for the Dauria Aerospace small satellite program based in Skolkovo, Moscow, Russia, and the NASA Ames Research Center, California. The Sensonor STIM210 and the STIM300 have been selected due to their unique combination of size, weight, power consumption and cost - making them extremely attractive compared to alternative solutions. Sensonor modules, highly reliable in the rigors of a space, are currently flying on multiple satellite programs in the U.S., Europe and Russia.
