Mars explorer 'Nozomi (PLANET-B)' experienced two earth swingbys in December 2002 and June 2003. During these swingbys period, radiometric data from Usuda tracking station were obtained, and orbit determination was carried out with an accuracy of a several km in position and a several mm/s in velocity. These results are compatible with the JPL orbit determination results. In this phase, Delta-VLBI observation were also experimentally performed, and fringe data can be obtained in several passes. In this paper, the preliminary evaluation of these Delta-VLBI data are briefly described.
