CHEFsat (Cost-effective High E-Frequency Satellite) is a 3U CubeSat to test and prepare consumer communications technology for use in space.

The growing range of devices, components and miniaturized technology available on consumer markets represents a boon for space exploration and cost management. CHEFSat specifically readies a consumer-grade radio frequency device for wider space use by testing its safety and effectiveness in a working CubeSat deployed from the International Space Station (ISS).

CHEFSat will test new, emerging millimeter wave components in space. Low cost, high performance, reliable IC devices that operate in E-band are now readily available. The main mission objective is to better understand the effects of weather and atmospheric conditions on E-band links.
