Abstract

The application of the AVLBI or VLBI switching technique for tracking extragalactic radio sources (ERS) and spacecraft which are at 10 deg or less angular separation offers a method for augmenting the current doppler navigation system. From general radio source catalogs, ERS have been selected which have promising spectral features and correlated flux values suitable for AVLBI tracking using the antennas in the Deep Space Network. A computer program has been written which reduces this list to those occurring in a specific region of the celestial sphere near the track of a deep spacecraft. Surveying two current missions, Pioneers 10 and 11, and two future missions, Mariner Venus/Mercury and Viking, reveals numerous opportunities for AVLBI,
