	The [http://info.hobbyengineering.com/specs/PX-GPSManualV1.1.pdf Parallax GPS (Global Positioning System) Receiver Module] is a fully integrated, low-cost unit with an on-board patch antenna. It provides standard, raw NMEA0183 (National Marine Electronics Association) strings or specific data from up to 12 satellites via its serial command interface. It can provide the current time, date, latitude, longitude, altitude, speed, travel direction, and other data.

It can provide the current time, date, latitude, longitude, altitude, speed, travel direction, and other data.

			The Parallax GPS module was designed to be used with a Basic Stamp and to use two directional information transmission. In order to use this chip with a PIC, we will need to read in long serial strings containing all data and then parse the strings for important data to export. The PIC can use RS232 to read in the serial data and store a large array of all characters, which can then be parsed by searching for comma seperated values.

	The NEMA strings this particular GPS outputs are GPGGA,GPGSA,GPGSV, and GPRMC in that order. For additional information about what data can be retrieved from these strings, go [http://home.mira.net/~gnb/gps/nmea.html here].

	The goal of the project was to set up a one-way connection between the PIC and the GPS Receiver Module, in which the PIC interprets the raw data collected by the GPS Receiver Module and displays it in a user-friendly format on a parallel LCD (Liquid Crystal Display). Specifically for this project, there are three sets of information that can be displayed: Position (Latitude / Longitude); Time & Number of Satellites Detectable; Velocity / Direction of Movement.
