Abstract
When a planet passes in front of a compact extragalactic radio source as seen from a radio telescope on Earth, timing measurements of the occultation can establish a radio-planetary frame-tie. Two of the three frame-tie parameters can be derived from a single occultation. Twenty-two occultation events in the period 1988-2000 have been found for the planets Mercury—Jupiter. Some of these events involve sources that are too weak or are too large to provide useful frame-tie measurements. However, seven events have good potential to yield frame-tie measurements in the 0-100 nanoradian range, improving on the current 150-nanoradian determination. The first event, an occultation by Venus in July 1988, has been successfully observed.
