Navigation - Monitor latitude, longitude and altitude.That's not all - print the results graphically.

Also monitor Standard Deviation and effects of Selective Availability. The ability for user selectable HDOP/VDOP color thresholds for position averaging make a great utility.

Its sole purpose is to display graphically specific NMEA 0183 sentences and show the effects of selective availability (SA). VisualGPS (Freeware) incorporates many advanced features found in professional programs. We recommend that you download VisualGPSView. Suggest donation $5 USDĬurrently VisualGPS is over 10 years old! NMEA support is only limited to GPS NMEA strings (Not GLONASS or Galileo). If you like VisualGPS and would like to support more products like these, please donate.

NMEATime2 will use digital filtering (the red line you see in the Time Difference Plot - see below) and discipline the PC clock to this reference.

As you would expect, there are delays between the 1PPS epoch and the RS-232 causing software jitter. NMEATime2 will use the NMEA string (GPGGA) transmitted from the GPS, time tag the first character of the that command and use this as a timing reference. In the USB world, it’s referred as a CDC (communication device class) device.

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.

The price for NMEATime2 is $20.48USD If you purchase NMEATime2, we will send you a registration key via email within 48 hours. NMEA files consists of standard NMEA sentences in text ASCII characters. NMEA Recording and Playback - Record NMEA directly to a file or read NMEA from a file.NMEA Command Monitor - View NMEA sentences as they are received.Position Plot - Monitor latitude, longitude and altitude averages.The signal quality window will grow or shrink to accommodate number of satellites in view Signal Quality/SNR Window - Monitor satellite signal to noise ratios and see them graphically on the screen.Scatter Plot - The scatter plot shows individual position samples referenced to several type of reference types, next sample, average or user defined.

Azimuth and Elevation Plot - View all satellites that are in view.NMEA/GLONASS - Supports GPS NMEA and GLONASS NMEA.Its sole purpose is to display graphically specific NMEA 0183 sentences for GPS and position analysis. VisualGPSView (Freeware) incorporates many advanced features that show the status of the GPS receiver via the NMEA 0183 protocol.
