Embodiment Construction
[0097] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0098] For convenience, the receiver in the following refers to the baseband processing chip of the global positioning system receiver, or a component that realizes an equivalent function. Assuming that the baseband receiver needs to search for all satellites 1 to 32, the baseband chip has 12 acquisition and tracking channels. Baseband chips with other numbers of acquisition and tracking channels can be deduced by analogy. The basic idea of the present invention is the same for baseband chips with different numbers of search and tracking channels, but some parameters are slightly different in specific implementation.
[0099] figure 1 A schematic diagram of an existing satellite search scheduling method is described. ...
