Description:
 
1. Get 51 STM32 microcontroller routine
2. with a USB interface, you can watch the computer
positioning effect directly phone line.
3. with the passive ceramic antenna and passive antenna
amplifier, make better use of the individual effects.
4. with SMA interface can be directly connected to an
active antenna SMA
5.Size:39*25.5mm
       GPS second pulse signal pps one second, its role
is used to indicate the time of the whole second, and
the moment is usually marked with the rising edge of
the PPS pulse. Because GPS can give UTC time, but
the user will receive a time delay, then in order to fine
timing, the introduction of the rising edge of the PPS
signal to mark UTC the whole second moment, the
accuracy can be nanoseconds, and there is no cumulative
error.
