By multiplying travel time by the speed of light, the navigation set determines the exact range to each satellite. By calculating the range to four satellites, an exact 3D position is calculated. The navigation set calculates speed by measuring the rate of change of the RF signals. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS 9-21.
