A system for determining the attitude of an airborne or spaceborne platform such as a terrain image sensor or an energy beam pointer includes a digital image correlator for comparing successive overlapping, instantaneous images of the terrain which are recorded by a second, two-dimensional image sensor whose image plane is oriented parallel to that of the platform or terrain image sensor. The second sensor generates an instantaneous master image and a subsequent slave image which at least partially overlaps the master image in terms of the terrain which is viewed. The master and slave images are approximately registered and a correlation is performed. A plurality of points on the slave image are correlated with the corresponding terrain points on the master image. The relative orientation of the slave image with respect to the master image characterizes the attitude change of the platform. The technique also reveals changes in altitude and velocity of the platform when mean altitude and velocity are known. The image produced by the terrain image sensor or the attitude of the beam pointer can be altered on a real time basis using the information relating to the change in platform attitude, or the master and slave image data can be recorded for subsequent use in modifying the image data recorded by the terrain image sensor. A multispectral scanner is employed to detect in advance regions that cannot be properly imaged due to clouds and the like and a computer controlled mirror directs images onto the sensor from regions that the scanner has determined to produce meaningful image data.

A method of determining changes in the yaw, pitch, roll or elevation of an airborne or spaceborne platform which moves along a flight path above the earth comprising the steps of: (A) generating a first set of data representing picture elements of a first two-dimensional image of said surface at a first point along said flight path such that the data representing all of the picture elements of said first image are generated substantially simultaneously; (B) generating a second set of data representing picture elements of a second two-dimensional image of said surface at a second point along said flight path closely spaced from said first point such that at least a portion of said images overlap each other, and wherein the data representing all of the picture elements of said second image are generated substantially simultaneously, said picture elements varying in intensity in accordance with their respective locations on the corresponding images, the corresponding picture elements of the first and second images in the overlapping portions thereof being offset from each other by an amount related to changes in the yaw, pitch, roll or elevation of said sensor; (C) correlating a plurality of corresponding picture elements of the first and second images in the overlapping portion thereof, the relative positions of the correlated picture elements representing the changes in the yaw, pitch roll or elevation of said sensor; and, (D) calculating the condition of coplanarity using the relative positions of the correlated picture elements.
