Title: INTELLIGENT GNSS POWER-SAVING DEVICE, POSITIONING SYSTEM, AND METHOD
Abstract:
An intelligent GNSS power-saving device (100), a positioning system, and a method. The intelligent GNSS power-saving device (100) is applied to a GNSS positioning system of a mobile terminal. The GNSS positioning system comprises an ELNA module (102) and a GNSS chip processing module (103). The intelligent GNSS power-saving device (100) is connected between the ELNA module (102) and the GNSS chip processing module (103). The intelligent GNSS power-saving device (100) is configured to monitor satellite signals from the ELNA module (102), and when detecting a satellite signal, instruct the GNSS chip processing module (103) to enter a sleep mode. The intelligent GNSS power-saving device (100) makes the GNSS chip processing module (103) work when there is a satellite signal, and makes the GNSS chip processing module (103) enter a sleep mode when there is no satellite signal, so that the problem of large power consumption and production of a lot of heat of the mobile terminal caused by the GNSS positioning system keeping a search state when there is no satellite signal.
