Abstract

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 tothe processing unit; and a power management interface coupled to the processing unit for controlling the convertion of the satellite navigation receiving device between a plurality of operation states. The satellite navigation receiver of the present invention can switch between the working state and the idle state. The energy consumption of the satellite navigation receiver can be reduced when the satellite navigation receiver performs in an idle state. In addition, when the moving speed of the satellite navigation receiver is accelerated, the processing unit can improve the frequency for updating the geographical position. Therefore, the effeciecy of the satellite navigation receiver can be improved.

Description

technical field [0001] The invention relates to a satellite positioning system, in particular to a satellite navigation receiving device and a control method thereof. 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 and velocity 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 satell...
