Amundsen-Scott South Pole Station uses communications satellites that serve as relay stations, receiving radio signals from one location and transmitting them to another. The United States Antarctic Program utilizes the satellites for the transfer of South Pole science, operational, and weather data, as well as Internet, telephone, and email services.

South Pole satellite schedule forecasts are published weekly. NASA’s satellite schedules occasionally change after publishing; check the Weekly Satellite Service Schedule before planning communications sessions with South Pole.
