Suomi and Robert Parent at the University of Wisconsin. After entering a geostationary orbit at {{convert|23000|mi|km|abbr=on}} above Earth, initially in orbit over Ecuador, it transmitted weather images from the Western Hemisphere, as well as other data, to ground stations, including well as video feeds for television broadcasting. "For the first time," historians would note later, "rapid-imaging of nearly an entire hemisphere was possible. We could watch, fascinated, as storm systems developed and moved and were captured in a time series of images. Today such images are an indispensable part of weather analysis and forecasting." [3] It was the first satellite to use frequency-division multiple access which accepted multiple independent signals and downlinked them in a single carrier. The spacecraft measured {{convert|56|in}} in diameter, {{convert|57|in}} high and weighed {{convert|750|lb|kg|abbr=on}}.[4] The ATS-1 satellite was used during the 1967 international television broadcast Our World, providing a link between the United States and Australia during the program. The ATS-1 would remain operational for more than 18 years, until April, 1985.[5] FeaturesThis satellite was cylindrical, with a diameter of {{convert|142|cm|in|abbr=on}} and a height of {{convert|135|cm|in|abbr=on}}; an additional {{convert|270|cm|in|abbr=on}} in height was the engine cover. The surface was covered with solar panels, and the whole satellite was stabilized by rotation. InstrumentsA total of fifteen experiments were conducted during the mission:[6]
