Design of Assisted GPS Client Based on Wireless Network

To solve the positioning problem of the traditional Global Position System(GPS) under the weak GPS signal,the method of Assisted Global Position System(AGPS) based on General Packet Radio Service(GPRS) is AGPRS wireless communication is implemented by adding communication protocol into GPS module,and information required by the AGPS receiver is transmitted through GPRS.Hardware components and software design of network transport protocols are separately introduced.Testing results show that this system not only can connect to lnternet rapidly and improve the signal capture capability of GPS receiver under the weak GPS signal sharply,but also can accelerate the fixing speed of GPS receiver.
