Abstract
During the Jupiter encounter of Pioneer 11 in December 1974, a limited amount of simultaneous two-way and three-way doppler was obtained. It was demonstrated in this study that, based on a very short arc (two weeks) of differenced doppler (quasi very long baseline interferometry or QVLBI doppler), the B-plane predictions were as good as 200 km at E-1 day and 400 km at E-3 days. During the two solar conjunctions of Pioneer 10 and 11, which occurred in March 1975, several passes of QVLBI doppler were obtained and analyzed. The data quality of QVLBI doppler was found to be two to three times better than the conventional two-way doppler when the Sun-Earth-probe angle was less than 5 degrees.
