Abstract
A device for measuring the heading error of a missile, comprising two afocal systems for a taking-in-charge field PC and a cruising field CR, in front of a double prism, with a central prism and a peripheral prism of the same angle bonded together with their dihedrals opposed. The double prism is in front of a focusing lens in the focal plane of which are disposed four detectors. When one detector sees the PC field, the other detector sees the CR field. An analog switch permutes in a circular fashion a processing device to the PC channel or the CR channel, for delivering missile heading error measurement signals.
