We can say that now human life has been inseparable from GPS, people living at home need to use GPS location services to find their own living around the various services, car travel route requires the use of GPS for navigation, GPS is used to find friend around you. In short, GPS has been integrated into all aspects of our lives.. GPS positioning ranging system master controller selects CortexM3 series ST 39。 board has three keys , one of which is the reset button, the other two are ordinary function keys ,there are three LED lights , one is power indicator , the other two are for the testing system 。 this system es with realtime clock module , which can still keep the clock chip operation with board lack of power( but did not seem to present how to use ) .Finally there are a JTAG download interface and the power module, which will make 5V power turn into a power, because the STM32 chip operating supply voltage requirements , JTAG interface is used in downloading and online debugger . Keywords: The board of minimum circuit system。GPS。全球定位系統(tǒng)是美國率先研發(fā)的,從 20 世紀(jì)七八十年代開始由美國軍方國防部率先使用的,最后發(fā)展到各個(gè)民用領(lǐng)域的
