The present invention discloses a satellite navigation equipment, a satellite navigation receiving device and a control method thereof. The satellite navigation receiving device comprises: a processing unit for positioning the satellite navigation receiving device according to a plurality of satellite signals; a clock generator coupled to the processing unit used for providing a reference clock to the processing unit; and a power management interface coupled to the processing unit and the clock generator and used for controlling the convertion of the satellite navigation receiving device between a plurality of operation states, wherein the operation states comprise a dormant state when the processing unit powers off and the clock generator powers-on. The satellite navigation receiver of the present invention can perform the plurality of operation states according to the needs of user and a system. Therefore, the effeciecy of the satellite navigation receiver can be improved. In addition, the energy consumption of the satellite navigation receiver can be reduced when the satellite navigation receiver performs in an idle state, a dormant state or a close state.
Description
technical field [0001] The invention relates to a satellite positioning system, in particular to a satellite navigation receiving device and a control method. Background technique [0002] A satellite navigation system, such as a global positioning system (GPS), supports a satellite navigation receiver, such as a GPS receiver, to determine the position of the satellite navigation receiver according to satellite signals. The Global Positioning System may include a constellation of more than 24 GPS satellites orbiting the Earth. At a particular time and at a particular location on the Earth's surface, at least four GPS satellites may be visible. Each GPS satellite continuously broadcasts GPS signals at a preset frequency. GPS signals contain the time and orbiting information of the satellites. The GPS receiver can simultaneously receive GPS signals sent by at least four GPS satellites. Based on the time and orbit information of at least four GPS satellites, the geographic...
