【Abstract】 Application of GSM(Global System for Mobile Communication) short message in GPS(Global Positioning System) is studied. Performance of receiver of Motorala UP OEM and TC35 terminal of Simens are introduced. Mscomm Control of Microsoft is used to perform serial communication and PDU(Protrocol pescription unit) model short message is sent based on AT instruction. Experiment result shows that the system has achived the design requirement and realized the basic desired function.更多还原
