  Finding a suitable very long baseline (VLBI) interferometer geometry is a key
task in planning observations, especially imaging sessions. The main
characteristic of the quality of VLBI imaging data is the (u, v)-coverage. In
the case when one or more radio telescopes are located in space, this task
becomes more complex. This paper presents a method for recovering the optimal
orbital parameters of space radio telescopes for a given desired (u,
v)-coverage, which in turn is the inverse task of searching for the optimal
geometry and orbital configurations of space-ground and pure space VLBI
interferometers.
