Abstract : Many electronic dynamic positioning systems that use a variety of technologies, such as laser ranging, UHF signal ranging and satellite ranging, are currently available. With the advances in technology, these systems are undoubtedly becoming more and more accurate. In fact, real-time submeter accuracy using the differential Global Positioning System (GPS) in a boat, aircraft, or ground vehicle is not unrealistic. However, verifying positional accuracy at this level of accuracy of a moving platform is difficult. Close- range terrestraial photogrammetry offers a proven and accepted method for this verification, using mostly off-the shelf components and technology. Such a system is being developed at the U.S. Army Engineer Topographic Laboratories. electronic positioning systems, verification, truth system, photogrammetric test system.
