The Navstar Global Positioning System (GPS) is an example of a spread spectrum communication system in which it is necessary to receive data from multiple satellite signal sources. The long range and limited radiated power of the Navstar satellites, together with the possibility of additional interference sources, results in a very stringent receiver specification as the signal level at the receiver is well below that of thermal noise. A considerable improvement in the signal to noise and interference ratio (SNIR) of a GPS receiver can be obtained by utilising adaptive antenna technology. Adaptive arrays have this ability to enhance SNIR because they are designed to reduce the sensitivity automatically towards jamming sources of unknown or variable direction and generally modify or adapt their beam patterns to optimise performance
