Example Embodiment
[0035] Example 1:
[0036] Such as figure 1 with figure 2 As shown, the GPS receiver of this embodiment includes a user terminal and a server connected through a mobile communication network. The user terminal is a mobile terminal and includes a radio frequency front-end module, a controller module, a data buffer module, and a wireless data transmission module.
[0037] Such as figure 1 with figure 2 As shown, the positioning process of the GPS receiver in this embodiment is as follows:
[0038] 1) The user end is in low power consumption mode by default. The user end sends a positioning request to the server at a certain moment. Each module of the user end starts to work. The RF front-end module outputs intermediate frequency data at a sampling rate of 16.368MHz with a bit width of 2bit. The intermediate frequency data is written into the data buffer module under the control of the controller module. At the same time, the controller module reads the intermediate frequency data o...
