Antennas by GD Enable 'Early Science' for What Will Become the World's Most Advanced Radio Telescope

  • Highly specialized, scientifically advanced antennas come together to capture never-before seen details about the cosmos
Newton, N.C. - Thirteen 12-meter antennas manufactured by General Dynamics SATCOM Technologies have been successfully installed at the 16,500-foot-high Chajnanator plateau in Chile, home to the Atacama Large Millimeter/submillimeter Array (ALMA) astronomical observatory. Located in the Andes mountains, the 115-ton, highly specialized antennas form part of an 11-mile-wide international astronomy project. When it is completed in 2013, scientists will use the observatory to study portions of the universe at a level of detail that is beyond what current astronomical technologies provide, studying the origins of galaxies, stars, and planets.

Now, in a preliminary step, the General Dynamics-built antennas are being linked together for the first time with others made in Europe and Japan to begin operating as a single radio telescope, enabling initial scientific experiments or 'early science.' One top-rated science experiment will use ALMA to unearth the behavior of about 50 of the most massive black holes in the universe previously hidden in the dusty material of their galaxies.

"The installation of the General Dynamics antennas on the Chajnanator plateau represents a significant achievement for the North American portion of the ALMA project," said Brian Schrader, senior director of Engineering and Major Projects for General Dynamics SATCOM Technologies. "We've provided the majority of the antennas now allowing scientists to pursue projects that use ALMA's eyes to make large leaps in exploration."

"With ALMA poised to commence historic early science observations using at least 16 of its final 66 antennas, it is already the world's most powerful astronomical observatory at millimeter wavelengths. We're grateful to the entire North American ALMA antenna team, of which General Dynamics SATCOM Technologies is an integral part, for working so hard to make this day possible," said Mark McKinnon, North American ALMA project director at the National Radio Astronomy Observatory (NRAO).

In addition to its antennas at the high site, General Dynamics has delivered another four antennas now in various stages of customer acceptance testing at the at the ALMA Operations Support facility, 7,000 feet below the Chajnanator plateau. Once complete and ready for operation, the antennas are carried by a custom-built transporter to the plateau where each is attached to a concrete platform and connected to electrical power, fiber optics and other services.
