Claim Text:
1. A method for calculating numeric output error values for an image, the image having a corresponding set of output correction values, the method comprising: receiving metadata corresponding to the image, wherein the image has been captured by a sensor on a satellite, the metadata including a plurality of input values for corresponding input parameters, the input parameters corresponding to conditions related to the sensor of the satellite at the time the image was captured, each input value including an input measured value, an input mean error, and an input error standard deviation value; providing the plurality of input values to a symbolic error covariance propagation model, the symbolic error covariance propagation model including a symbolic covariance matrix that relates the plurality of input parameters to one another pairwise and in closed form; and generating a set of output error values from the symbolic error covariance propagation model and the plurality of input values, the set of output error values identifying a reliability of the set of output correction values that correct for velocity aberration which has translated the image away from an expected location.
