Satellite-1 (ADEOS-1) by Japan. The second 11-meter antenna was installed in 1995 on University-owned land within walking distance from the Geophysical Institute, and the 9-meter antenna replaced the original ground-station antenna in 2017. The ground station's prime polar location in Fairbanks enables the facility to service high-inclination, polar-orbiting, Earth-imaging spacecraft. The systems operate 24 hours a day, 7 days per week. The facility has evolved over the past 20 years into a full-service station, providing telemetry downlink, uplink, command and two-way coherent tracking services as one of 15 major members of the international Near Earth Network, which is managed by NASA’s Goddard Space Flight Center. The facility processes, and distributes raw data from remote-sensing satellites, servicing NASA and foreign agency satellites in support of scientific and operational research and applications. GeoData center The Alaska Satellite Facility managed the Geophysical Institute's GeoData Center for many years. In 2016, management of the center was transferred out of the Alaska Satellite Facility. Its new website is here.
