What NRAO Does

The National Radio Astronomy Observatory designs, builds and operates the world's most sophisticated and advanced radio telescopes. Scientists from around the world use these powerful tools to study the Sun, planets and other objects in our own solar system, as well as distant stars, galaxies, and other mysterious objects many millions, or even billions of light-years away.

The Unofficial Mission Statement of the ALMA WCA Production Group:

NRAO provides state of the art local oscillator designs to our integration center partners on time and without defect, incorporating the latest methods and procedures as new knowledge is gained and methods are refined.The NRAO FELO group provides the expertise to design, build, refine, and deploy these oscillators to our partners as well as provide technical assistance and device improvements as they are continually developed.
