Design and development of GSM and GPS tracking module

The GSM and GPS technologies and their applications have great demand in the consumer market areas like automobile, surveillance and navigation. The GSM and GPS technologies will be integrated into a single board which can be used for various wireless applications. The integrated GSM and GPS module will be made using SIM808 by SIMCom which has both GPS and GSM engines. Schematic of different parts of module are designed. The circuit design of Regulator, SIM card interface, Antenna interface, USB interface, Indicator circuit and other parts are done using ISIS schematic tool of Proteus Design Suite v8.3. Footprints of all the components are created and PCB Layout of SIM808 module is designed using ARES tool. Operation of module is observed in different operating modes. The developed module is interfaced with PC to test the features of GSM and GPS by sending AT commands. Developed module can be used in applications like tracking and automobile.
