Abstract
A VLBI survey at 2.29 GHz of the northern polar cap region (declination > 69 deg) has been conducted using a baseline consisting of the NASA Deep Space Network (DSN) sites at Goldstone, California and Madrid, Spain. The purpose of this survey was to identify sources in the northern polar cap region which possess milliaresecond components. High declination VLBI sources provide valuable geometric coverage for determining the spin axis components of baselines. Out of 48 candidate sources selected from the Bonn 5-GHz survey, 42 were detected to have compact structure on the California/Spain baseline at the 2.29-GHz observing frequency. This polar survey is part of a more general VLBI sky survey.
