Cesium Mission 1 (CM1) is CesiumAstro's first mission to launch and operate our own hardware in space. CM1 provides an on-orbit platform consisting of two satellites for customer experiments that push the boundaries of small-satellite communication. In addition, it gives CesiumAstro the capability to demonstrate advanced features of our technology such as dynamic-waveform switching and dynamic-link optimization. With the launch of CM1, CesiumAstro now has a complete commercial phased array communication system as well as an intersatellite link in LEO.

The CM1 ground segment includes CesiumAstro ground stations and the GlobalStar network for persistent command and telemetry. CesiumAstro is developing ground stations at office locations in Texas and Colorado. These ground stations can communicate with the spacecraft over both payload and telemetry links.  Additionally, the ground stations are remote-operable on the CesiumAstro network across CesiumAstro locations.
