Ground Station is a new media artwork created by Canadian artists Daniel Jolliffe and Jocelyn Robert. Their work watches and responds to the movement of Global Positioning System (GPS) satellites (including their current azimuth, elevation, and signal strength.) As satellite data is received, the artwork inverts the traditional use of this information by processing and transforming it into musical notation. This unique, continuous musical composition is then played live, on an electronic Disklavier piano. -Back of the cover.
