In 2020, a project between AMSAT-UK, AMSAT-NL, and Swiss universities got under way with the aim of equipping two Swiss satellites — for now under the CHESS name — with linear amateur radio transponders.

The CHESS (Constellation of High Energy Swiss Satellites) project includes two satellites, which will be built simultaneously and later launched as a constellation.
