Patent ID: 7233281

Claim:
A group global positioning system, comprising: a plurality of positioning signal processing devices with a global positioning function, each comprising a positioning signal processing module for executing the global positioning function and receiving digital global positioning information sent by a satellite while executing the global positioning function, a first signal conversion module for performing digital-to-analog conversion on the digital global positioning information and outputting analog global positioning information, and a second signal conversion module for performing analog-to-digital conversion; a plurality of radio signal processing devices corresponding to the positioning signal processing devices and outputting, by radio transmission, the analog global positioning information outputted by the first signal conversion module; and a configuration module, varying a quantity and an attribute of the positioning signal processing devices; wherein, with one of the corresponding radio signal processing devices, one of the positioning signal processing devices sends to the remaining ones of the positioning signal processing devices the analog global positioning information outputted by the first signal conversion module, allowing the second signal conversion module of the remaining ones of the positioning signal processing devices to perform the analog-to-digital conversion on the analog global positioning information and recover the digital global positioning information, thus enabling the positioning signal processing module of the remaining ones of the positioning signal processing devices to execute the global positioning function and display related information.
