Scientific paper

The imaging capability of Quasat is remarkable. In conjunction with a large ground array it will produce images as complex as the best that the VLA has ever produced. At 22 GHz the resolution will be 0.075 milliarcseconds (mas), the field of view about 15 mas, and it will be possible to make noise limited maps of complex objects.
Quasat is essential for mapping southern declination objects. Without Quasat, even the simple core-jet source cannot be mapped at declination -60° (see Figure 7).
It will be possible to make some maps with observing times as short as 6 hours; the very best maps will require 48 hour observations.
The Extended European VLBI Network and the VLBA in conjunction with Quasat will produce maps of comparable quality with either ESA or DSN telemetry stations.
