The embodiment of the invention provides a satellite navigation device and a low-power-consumption processing method thereof. The device comprises radio frequency hardware and baseband processing hardware. The baseband processing hardware comprises a baseband signal processing unit and a CPU unit. The CPU unit comprises a power consumption control unit. The power consumption control unit is used for enabled control of a low-power-consumption mode of the satellite navigation device. The radio frequency hardware and the baseband signal processing unit are closed and the CPU unit is in an intermittent operation state when the device enters the low-power-consumption mode. The radio frequency hardware and the baseband signal processing unit are opened and the CPU unit is in a normal operation state when the device exits the low-power-consumption mode. According to the embodiment of the invention, on the premise that the high performance of the satellite navigation device is ensured, the operation power consumption of the satellite navigation device is reduced.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of satellite navigation, in particular to a satellite navigation device and a low power consumption processing method thereof. Background technique [0002] Satellite navigation technology is a hot field for the development of various aerospace powers. In order to maintain the advancement and effectiveness of navigation systems, countries around the world are actively promoting and developing related technologies of satellite navigation systems. At present, there are mainly four communication systems that can provide precise satellite positioning and navigation in the world, namely the Global Positioning System (GPS) of the United States, the GLONASS positioning system of Russia, and the Galileo (GALILEO) of Europe. ) positioning system and China's BeiDou Navigation Satellite System (BDS, BeiDou Navigation Satellite System). [0003] The satellite navigation application industry is...
