Abstract: One method is introduced to realize high accuracy auto collimation for mapping instruments via adding accessories without a refit. Collimating ocular is used for close quarters auto collimation, while projector is used for far-forth quarters auto collimation. Moreover, the design and analysis are referred to concretely, expanding the using range of mapping instruments in effect.

Key words: Ocular, Collimation, Projector
