Alaska Satellite Facility
Delivering Remote Sensing Data Since 1991

The ASF Satellite Tracking Ground Station 

  • Serves as the leading NASA ground station in Alaska.
  • Services polar-orbiting, Earth-imaging spacecraft from ASF's prime polar location (see station mask).
  • Is one of the world's top university-operated ground stations.
  • Operates three antennas on behalf of NASA: an 11-meter S/X-band antenna installed in 2013, an 11-meter S/X-band antenna installed in 1995, and a 9-meter S/X-band antenna installed in 2017.
  • Provides telemetry downlink, uplink, command, and two-way coherent tracking services as one of 15 primary members of the international Near Earth Network (NEN), which is managed by NASA’s Goddard Space Flight Center. The NEN provides services to orbital spacecraft from ground stations around the world.
  • Operates 24 hours a day, seven days a week.
  • Distributes data focused on, but not limited to, synthetic-aperture-radar (SAR) data, primarily to scientific users.
