Very Long Baseline Array

The Very Long Baseline Array ( VLBA ) is a radio interferometer, by the methods of VLBI radio observations of astronomical objects can be obtained with high angular resolution with the.

The ten antennas of the VLBA, each with 25 m diameter and 240 tonnes are distributed over ten sites in the U.S.:

  • Mauna Kea Observatory, Hawaii
  • Owens Valley Radio Observatory, California
  • Brewster, Washington
  • North Liberty, Iowa
  • Hancock, New Hampshire
  • Kitt Peak National Observatory, Arizona
  • Pie Town, New Mexico
  • Fort Davis, Texas
  • Los Alamos, New Mexico
  • St. Croix, U.S. Virgin Islands

The greatest distance between these sites is 8611 km. The antennas have the receiver for ten frequency bands between 300 MHz and 86 GHz. Due to the long baselines between sites reached the VLBA, depending on frequency, an angular resolution of less than a thousandth of a partial arc second.

The construction of the VLBA was started in 1986. The VLBA was inaugurated in 1993 and is operated by the National Radio Astronomy Observatory of the United States. The headquarters is located in Socorro, at the Very Large Array site.
