Gun-Pointing Vector Instrumentation System is Revolutionary, Portable, Rugged

摘要

The technology offered by laser rangers and high-speed computers no longermeasure accuracy in yards, but in tenths of an inch. These accuracies are being achieved at U.S. Army Yuma Proving Ground (YPG) via instrumentation known as the Gun-Pointing Vector Instrumentation System (GPVIS). The GPVIS program has taken an evolutionary path that led from the original concept of triangulation technique to a trilateration technique. The original GPVIS concept was a high-resolution optical imaging system that uses triangulation to precisely measure small changes in gun barrel position, distortion, pointing, and alignment.
