GSM (Global System for Mobile Communications)/GPS (Global Position System) module, GPS comprising same and use method thereof

Abstract

The invention discloses a GSM (Global System for Mobile Communications) / GPS (Global Position System) module, a GPS of a mobile communication terminal, comprising the GSM / GPS module and a use method thereof. The GSM / GPS module comprises a GPS module and a GSM module, wherein the GSM module is a GSM baseband chip which comprises a GPS navigation information computation module, a GPS application module and a GSM fundamental operation system module. The use method of the GPS location system comprises the following steps of: S1. issuing a GPS location command by the GPS application module to start the GPS navigation information computation module; S2. starting a GPS chip by the GPS navigation information computation module; S3. receiving measurement data the GPS chip by a radio-frequency antenna; S4. transmitting the received measurement data to the GPS navigation information computation module by the GPS chip; S5. calculating the measurement data and transmitting information to the GPS application module and storing the information in the fundamental operation system module by the GPS navigation information computation module; and S6. issuing a command to turn off the GPS system by the GPS application module. The invention facilitates the update of a GPS navigation program and the expansion of the system.

Description

technical field [0001] The invention relates to a GPS positioning system, in particular to a GSM / GPS module combined with a GSM wireless module and a using method thereof. Background technique [0002] Ordinary GPS (Global Positioning System: Global Positioning system) chips need to receive data from the radio frequency antenna for measurement and processing, and then complete positioning through complex navigation data calculations, and also need to store satellite ephemeris information. The GPS chip based on host computing, such as the SIRFStar III GSD3 launched by SIRF in the United States, is the first to integrate all the baseband, analog and RF circuits necessary for simultaneous processing of GPS and assisted GPS on a single CMOS (Complementary Metal Oxide Semiconductor) die The product. In the past, devices used to place discrete CMOS baseband and silicon germanium radio frequency dies in the same package. After integration, GSD3t adopts 4×4×0.68mm TFNGA package. ...
