Time-optimal slewing for orbiting astronomical observatories such as the Swift gamma-ray burst detector and observatory must include constraints to protect delicate optical sensors from accidental exposure to high-intensity sources such as the Sun, Earth and Moon. This paper considers the problem of slewing a spacecraft in minimum time in order to align an onboard telescope with a particular target, with one or more path-constraints that maintain a minimum angular distance between the optical sensor axis and the high-intensity sources. The problem is solved via a pseudospectral method, with solutions showing a relatively simple control-switching structure.
