International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / Navigation is the means by which a craft is given guidance from one known location to another. Since the global positioning system (GPS) is very accurate positioning system, a personal navigation system based on GPS is very effective. From the user point of view, the function of this system is to provide real-time positioning and timing data to the user. The system consists of 6-channel GPS oncore receiver, a system controller & processor (SC&P) card, a programmable liquid crystal display (LCD) and a keyboard. The 6-channel GPS OEM card receives GPS signal from six different satellites at a time. After processing the received GPS signal, it gives the result & status message to its output port in a typical data format. The system controller & processor card receives this message from the GPS OEM card and extracts the useful positioning & timing information in binary form. After that it processes the data and displays it on the LCD display. The keyboard has used to select the desired positioning & timing information on the display.
