Abstract
This is a 2 GRTs VSOP survey experiment.

Fringes were clearly detected on all three (1 ground-ground and 2 ground-space) baselines.

Since only 3 antennas (including Halca) available, imaging was done without any amplitude self-cal.

Model fitting was tried to fit the central region only with a circular Gaussian component while keeping 24 clean components of remaining structure.

For both calibrators 0528+134 and 0808+019, strong fringes were seen on the ground baseline (HartRAO - Noto) of 6,000km with correlated flux densities of 0.95Jy and 0.40Jy, respectively.

The data after 21:24:01 was useless because both u and v were wrongly set zero for ground baseline. Fringes still can be seen for both J0607-08 and 0808+019. The reason is unknown.
