A GPS receiver system to determine and display a geographical differential Global Positioning System (DGPS) location where the components of the system are interconnected with an airwave infrared (IR) link. The system includes a GPS Smart Antenna receiver module to determine the geographical location of the module, a DGPS radio receiver to receive an airwave radio frequency DGPS signal having DGPS correction information, and a personal computing display to run an application program and to display the geographical DGPS location and application information that is useful to a user. The GPS Smart Antenna receiver module and the DGPS radio receiver are switched on and off from the personal computing display through the airwave IR link.
