System and method for advanced navigation

A navigation system comprising:

• one or more navigation subsystems configured to determine a position of a platform;
• a first processor configured to receive one or more outputs of the one or more navigation subsystems and generate a navigation solution;
• a sensor configured to generate a ground image;
• and
• a second processor configured to:
• process the ground image into one or more of a plurality of textures to generate a processed ground image;
• determine an estimated location of the ground image;
• partition the processed ground image into a plurality of ground image sub regions;
• retrieve a reference image from an atlas of reference images, each reference image in the atlas having an associated accuracy, resolution, and projection, the reference image having a position, projection, and extent determined based on the estimated location and a ground image projection of the ground image;
• generate a plurality of matching statistics comprising a matching statistic for each ground image sub region by comparing the ground image sub region to a portion of the reference image;
• calculate a relative position of the ground image with respect to the reference image based on the matching statistics;
• determine critique data associated with at least one of the one or more navigation subsystems based on the relative position of the ground image with respect to the reference image and a position of the ground image determined using the at least one navigation subsystem, the critique data comprising at least one of an error or a status of the at least one navigation subsystem based on an analysis of the position of the ground image determined using the at least one navigation subsystem in view of the relative position of the ground image with respect to the reference image;
• and
• transmit the critique data to the first processor;
• wherein the first processor is further configured to adjust one or more parameters associated with the at least one navigation subsystem based on the critique data, the first processor configured to generate the navigation solution using the adjusted one or more parameters.
