WebGPS included a (currently disabled) feature called Selective Availability ( SA) that adds intentional, time varying errors of up to 100 meters (328 ft) to the publicly available navigation signals. This was intended to deny an enemy the use of civilian GPS receivers for precision weapon guidance. WebThe GPS signals are used in real time to synchronize his local clock and GPS time or UTC (USNO). The purpose of the measurement is usually either to synchronize an on-time pulse, or to calibrate a frequency source. To make use of this knowledge, the receiver must then generate a timed output signal.
