Note: The overall objective of the Applications Technology Satellite (ATS) program was to investigate and flight-test technological developments common to a number of satellite applications. Designers of ATS at Hughes Aircraft Company and the Goddard Space Flight Center built on the successful Syncom communications satellite design. Each of six ATS spacecraft carried a variety of communications, meteorology, and scientific experiments, in addition to providing a platform for evaluating three different kinds of spacecraft stabilization systems. ATS 1 was a synchronous-orbit spin-stabilized satellites.
