Abstract

After having adapted the Smithsonian Astrophysical Observatory (SAO) atmospheric phase monitoring system that was developed for the submillimeter array (SMA), IRAM is currently refining the concept for a future permanent implementation on the northern extended millimeter array (NOEMA) site. This system is based on commercial low noise block attached to a satellite dish that receive signal from geostationary satellites. The baselines (one so far) amplitude and phase are processed to provide real-time statistical data in the direction of the satellite and give information about the atmospheric phase distortion experienced by the NOEMA interferometer antennas.
