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

Remote
Sensing Satellite-1 (ERS-1) data. The expected data volume for the station was 45 minutes total from ERS-1, JERS-1 and RADARSAT. In the operations stage, data flow rapidly increased due to changing requirements from flight agencies and government sponsors, and storage of online data and demand for SAR data was expected to rapidly exceed capacity. The Satellite-Tracking Ground Station launched in 1990, and in 1994 a Memorandum of Agreement (MOA) between NASA and UAF formed the ASF Distributed Active Archive Center (DAAC). The facility was renamed the Alaska Satellite Facility in 2003.

The launch of ADEOS-1 resulted in ASF simultaneously supporting four active missions until the loss of the two Japanese missions (ADEOS-1 in 1996 and JERS-1 in 1998), and the deactivation of ERS-1 with the launch of ERS-2 in 1996. In November 2002, the National Oceanic and Atmospheric Administration (
89:) appointed UAF as agent for the data acquisition, processing, and distribution to support the Japanese Advanced Land Observing Satellite (ALOS) mission, which featured Phased Array L-band Synthetic Aperture Radar (PALSAR). With the successful launch of ALOS in January 2006, ASF’s Americas ALOS Data Node (AADN) became operational in October that same year when the Japan Aerospace Exploration Agency (
141:) mission, which featured Phased Array L-band Synthetic Aperture Radar (PALSAR). Due to the agreements with many of the foreign agencies involved, at first much of the foreign-source DAAC data was restricted distribution to NASA-approved scientists only. But in 2015, the ALOS PALSAR data became unrestricted, and the Sentinel-1 data is also unrestricted.

In 1986, the Jet
Propulsion Laboratory requested and approved a quotation for the integration of a receiving ground station, the Alaska SAR Facility, at UAF. The Alaska SAR Facility was marked at a ribbon-cutting ceremony on April 24, 1991. Later that year, the facility began down-linking European
