Lunar Parallax Method of Astro Navigation

摘要

In considering the problem of the automatic navigation of long-range surface-to-surface missiles it soon becomes evident that the system must be 'unjammable' by the enemy. That is to say, the missile cannot be required to depend on information received on radio channels (of any frequency) to keep on course. Such methods can be easily confused by the enemy's broadcasting spurious signals. A system not subject to such maltreatment that would measure the change in the position of the moon relative to the stars due to the motion of the observer (the missile, in this instance) over the surface of the earth is proposed. The elements which such a system could have are described.
