GPS is examined in two parts. GPS receiver is the first part of it. It provides to take GPS signal from the satellite and send the information from its serial port. Its internal serial port sends the data through tx port. The data is sent via NMEA format so that it is needed to decode the NMEA format. In second part, in order to decode the signal NMEA format is introduced.
In the project, the MediaTek MT3329 GPS module is used. It can be seen in figure 1. The MediaTek-3329 is an ultra-compact POT (Patch on Top) GPS Module. This POT GPS receiver provides a solution that is high in position and speed accuracy performances, with high sensitivity and tracking capabilities in urban conditions. The module can support up to 66 channels and is designed for a small-form-factor device.
