Range Only Correlation System
(R OCS)—An all-weather terminal guidance
system that uses ranging information to
determine its pesition by comparfng two radar
images. The images are taken 90° apart end
m-r~ Wirh a reference (or prediction) of
Cc@resl edge informet”mn (bright @s) in the
mnge return ~g~l. The checkpoint is e
geographic refereme I-tkan, s.dded prier to
the mission, by which the vehicle can determine
course corredon.
