significant variations between different GPS satellite signals. Since most GPS receivers require signals from four or more satellites, many GPS navigation solutions (past, present, and future) may contain unexplained bias errors ranging from a few centimeters to several meters. Current GPS receivers presume GPS signals are identical and that range
