The Next Generation Celestial Reference Frame
Abstract
Astrometry is the fundamental cornerstone for all areas of Astronomy. The IAU adopted International Celestial Reference Frame (ICRF) consists of radio positions of 4536 quasars. In order to maintain and improve the accuracy of the ICRF, we require a next generation radio telescope with long baselines and high sensitivity such as the ngVLA.
