The SkyTraq output a pulse before every the UART data message.
Pin 98 should be configured as a GPIO interrupt for the pulse, to deal with the time difference of receiving the gps data to the message outputting over UART. We need this diff to adjust the time in the UART message before syncing the system time to gps time.
