More Information: The innovation of this proposed star tracker is
conceived by using spatial filtering with a concept
complementary to that of coronagraph for sun corona
observation, allowing to drastically reduce the size of
the shadow. It can also work close to antennas and
other part of the platform, which, when illuminated by
the sun, become secondary sources capable to blind the
star tracker.
