Several satellite navigation systems are currently in operation or are scheduled for deployment in the near future. These include the United States Global Positioning System (GPS), the Russian Global Navigation Satellite System (GLONASS) satellites, and the European Galileo satellites. In addition to determining the position and velocity of a receiver, signals from these satellites can be used to distribute time and frequency information and to compare clocks at remote stations. A number of different techniques are commonly used for these purposes, and we will describe these techniques in this article. Although the different satellite systems differ in technical details, the methods we will describe can be used with any one of them with only minor modifications.
