18 August 2014 Adding baselines at the Navy Precision Optical Interferometer
Author Affiliations +
The Navy Precision Optical Interferometer is an astronomical optical interferometer operating near Flagstaff, Arizona. A joint program between the United States Naval Observatory, the Naval Research Laboratory and Lowell Observatory, it has historically been involved in space imagery and astrometry. More recent work has pushed for the addition of more baselines. It is currently capable of co-phasing 6 elements, so the commissioning of additional baselines requires ease of use and reconfigurability. At the time of this publication, a seventh station has been added and the final commissioning work on an eighth and ninth station are being completed. These last two stations will increase the longest baseline to 435 meters. This paper discusses the work to date on adding these stations and provides details on increased capabilities.
