There are several ways to distort a GPS satellite signal; some are corrected by the Department of Defense and others can be corrected in your GPS receiver using real-time ground station correction signals. The only precision problem, which is left to you to control is Geometric Dilution of Precision. Controlling GDOP is the key to writing commercial-grade GPS applications. A small mathematical formula can be applied to determine the maximum allowable DOP for a particular application. The maximum allowable error should be the greatest possible value, which minimizes accuracy problems while maximizing operational conditions.
