Modeling Global Positioning System Effects in the TLC/NLC Model
Use of the Global Positioning System (GPS) can enhance the navigation of combat platforms and the guidance of munitions. This report presents a design for incorporating GPS into RAND's theater-level combat or nonlinear combat (TLC/NLC) model, which is used for policy analysis of military operations. The author's design looks first at GPS coverage, i.e., how position is located using one or more GPS satellites. Next, the author considers factors limiting the access of GPS-equipped assets to the system. Third, the author examines the benefits to assets so equipped: improved self-location accuracy, which enhances navigation and reduces fratricide; improved target location accuracy; and improved targeting of stand-off munitions. The final consideration is countermeasures against threats to GPS transmitters, receivers, and signals.
