You only need to be stationary if the periscope is turned away (not exactly on) from 000 or 180. If it is pointed straight ahead or aft then your speed has no influence on the result! This does however require that you turn your course to a little bit infront of the target. And it is best to be submerged, as the sub is less likely to make course deviations due to wave action. Turning is definitely a no-no.
