Astrocast's satellite is in the CubeSats category, which is a type of nanosatellite defined by a standard cubic shape measuring 10cm on each side. It consists of three units and is approximately the size of a shoebox. This satellite is for demonstration purposes, and a second one of the same type will be launched from India in January.

They represent the first in a long line of Astrocast satellites: they will be used to test the system that Astrocast plans to market, which will involve a further 80 satellites in orbit by 2022. This Internet-of-Things (IoT) system will connect millions of objects all over the Earth's surface. It will enable Astrocast clients to monitor infrastructure and facilities remotely and at a much lower cost than existing methods.
