Abstract:
1. A method of providing a relative navigation system comprising: projecting into space from a first object a grid comprised of a plurality of grid lines defining a first relative reference frame associated with a first origin point on the first object; repeatedly detecting the grid of a plurality of lines from a second object having a second relative reference frame associated with a second origin point on the second object; repeatedly determining a range from the second object to the first object based on the grid of lines forming the first relative reference frame; repeatedly determining over time the relative attitude between the first and second relative reference frames to form a plurality of relative attitudes; and adjusting at least one of the determined relative attitude and determined range of at least one of the first and second objects based on the determined range and relative attitude; wherein both of the first and second objects are moving objects and wherein one of the first and second objects is a target vehicle and the other of the first and second objects is a chase vehicle.
