I removed the following (apparently) non-canon description:
How An Astrogator Works:
The circular design of the "Astrogator" creates a 360 degree position reference with the starship at its center. The position pointer provides a manual representation of the vessels directional progress while the outward circles denotes fixed distance marks that can either be manually adjusted, by the pilot or automatically adjusted via the ships navigational computer. A secondary and third scale needle indicates the ships vector and axis point. By observing its position in relation to three corresponding floating scales on the instruments outer rim you can calculate the x, y and z axis to establish the vessels flight path. Since the device is tied into the helm control, manually moving either needle will cause the ship to respond in the indicated direction.
If a canon source can be cited, then it can be put back. -- Renegade54 05:52, 10 June 2008 (UTC)
