Abstract
Present novel and non-trivial systems and methods for embedding aircraft attitude data within a pixel data set and detecting inconsistent aircraft attitude information are disclosed. A pixel data set representative of the scene outside the aircraft is generated based upon the navigation data and the terrain data, attitude-exclusive data is generated based upon orientation data, and attitude-exclusive data is embedded into the pixel data set to form an embedded pixel data set. Attitude-exclusive data is comprised of attitude-exclusive pixel data having first and second pixel locations or attitude-exclusive ancillary data. Attitude-exclusive data is compared against separately-provided reference attitude data for the purpose of detecting inconsistent attitude information. Inconsistent attitude information is detected when at least one attitude measurement determined from either the attitude-exclusive pixel data or the attitude-exclusive ancillary data does not equal the respective attitude measurement of the reference attitude data.
