Abstract:	In this paper, the authors describe Augmented Reality (AR) and how the technology can enable new navigation capability derived from modern Global Positioning Systems (GPSs). Real-world test events in a challenging environment are described in this paper. Amphibious vehicles are uniquely tested because they must navigate at sea and on land through a difficult surf zone. During testing on Amphibious Assault Vehicles (AAVs) in 2009 and 2010 at Marine Corps Base Camp Pendleton, California, Cross-Track Errors (CTEs) were calculated for a number surf breach runs almost 1000 m offshore with multiple turns using AR navigation with commercially available civilian navigation hardware. The average distance from the center line of the planned track for AAVs over these runs was as low as two meters. This was over tracks laid out with turns and doglegs to enable modern maneuver concepts. The AAVs exited the water each time in nearly identical tracks to previous runs despite tidal currents and waves where often unequipped vehicles were far off track. Having a look ahead/drive-to–point, forced the operators to self correct for the effects of wind, wave, and current. This new accuracy paradigm has major tactical implications on amphibious operations planning and specifically in mine warfare. The technology can reduce the amount of area that mine warfare forces must clear of mines to allow safe transits. Research and development test results are presented.
