1. global positioning system signal capture method, the method includes the steps of:

  • Receive a global positioning system signal, comprise the complex data position, each data bit has a bit period, and each cycle comprises the plural number sample period;

    Construction one comprises the region of search of plural elements, a corresponding hypothesis side-play amount of each element and a hypothesis pseudo-code phase;

    Before the position conversion takes place, with the element value of described data bit substitution one people having the same aspiration and interest combination algorithm with each element that adds up;

    AndAfter the position conversion takes place, with the element value of described data bit substitution one difference people having the same aspiration and interest combination algorithm with each element that adds up;

    AndJudge one group of hypothesis side-play amount in the described region of search and suppose that pseudo-code phase is the global positioning system signal capture result according to the accumulation result of element value.
