However, the modern USB GPS looks to the PC as a USB to Serial driver that emulates the serial port. The majority of the USB GPS receivers will look to the PC as if it is a serial port. It’s getting more difficult to find a PC with a native RS-232 serial communication port, most GPS receivers that interface to a PC use a USB. Specifically, the rate output of NMEA message GPGGA and GPRMC. By charactering the arrival of NMEA messages, NMEATime2 uses advanced digital filters to minimize communication jitter and achieve the best reference to train the PC clock to.īecause of this, there are some requirements that need to be met. The control loop uses the same techniques in disciplining OCXO oscillators and atomic Rubidium clocks. NMEATime2 is set up as a system service where the PC clock is disciplined to the NMEA string from the GPS. NMEATime2 is PC time synchronization software that synchronizes the PC clock to the time from a GPS receiver.
