1. A computer method for calculating position and orientation of a first vehicle using georeferenced digital imagery taken remotely from a second vehicle, comprising the steps of:
transferring georeferenced digital images of earth from said second vehicle and storing said georeferenced digital images of earth in computer memory; acquiring images of earth at said first vehicle and storing said earth images in computer memory; executing a software application at an INR computer processor, said application comprising a plurality of software instructions stored on non-transitory computer-readable medium for instructing the INR computer processor to perform the steps of,
accessing from said computer memory said acquired images of earth from said first vehicle and said georeferenced digital images of earth from said second vehicle and comparing said acquired earth images to said georeferenced earth images at said INR processor by identifying tie-points in said georeferenced images of earth, andperiodically estimating a current and future position and orientation of said fir vehicle by said INR processor periodically updating a linear quadratic estimation of said current and future position and orientation of said vehicle with said georeferenced image tie-points.
