Abstract This is a 2 GRTs VSOP survey experiment. Good fringes were found to Halca during RZ pass as well as to two ground antennas all the time. Very weak fringes were seen during the 1 hr UZ pass, consistent with the DQA report. The uv-crossing points between two space baselines showed that the relative gains between two ground telescopes are good. If Halca is assumed to be okay, the whole amplitude scale is reasonable. This is also consistent with the fringes amplitude for the calibrator source (see below). Both imaging and model fitting went very well. A single circular Gaussian component model was used to fit the calibrated data. Strong fringes were detected for the calibrator (2255-282) on the ground baseline (HartRAO --- Mop) of 9,000km with a correlated flux density of 2.1Jy, quite consistent with the PLS results of 2.2Jy at about 7,200km.
