The attainable set of a linear control system can have both
smooth and not smooth boundary.
This smoothness property is known to be used to classify such systems.
One approach, suggested by A. I. Ovseevich in the case of
a smooth control set, is based on connecting smoothness of the
attainable set with spherical observability of the dual system.
This paper generalizes these results to a case of nonsmooth
control sets.
The corresponding property of spherical observability notion can be
treated as observability with several bearing-only observations.
