Note that the blue ellipses show only 2 seconds difference yet the offset is set to 3 seconds - that is a result of an internal timer that only updates the computer time display each second. Note that the XP version has an option to adjust the computer time backwards or forwards by 5 seconds in one second increments, and that becomes obvious when you see the detail in the UT Offset box (red ellipses). Note the layout has been altered (V16) but functionality remains similar. and adjusting it's clocklist.txt file to local NTP sources in your locality. If you want to run the calibration option,В I suggest downloading and doing timing comparisons using NTPMonitor from So, if our two GPS receivers that are far apart both have WAAS enabled they will still be pretty close, accuracy-wise, after the corrections are done.

These corrections account for GPS satellite orbital drift and clock drift plus signal delays caused by conditions in the atmosphere and ionosphere. This is, to keep it really simple, a system of satellites and ground stations that are used to provide GPS signal corrections.

Most GPS receivers support a protocol called WAAS (Wide Area Augmentation System). If they are so far apart that they are being affected by significantly different atmospheric conditions, all may not be lost. If they are too far apart to use the same GPS receiver but close enough together that they are affected by the same local atmospheric conditions, say, within a few miles of each other, it still won't be an issue as long as they use the same make/model of receiver and the same software. If two devices are close enough together to be connected to the same GPS receiver, say via Bluetooth, it really won't matter because they'll be getting the same signal and by using it will be sync'ed as accurately as that signal will allow. These are mainly related to atmospheric conditions from high in the atmosphere to anything affecting only local conditions. In the case of the extremely weak GPS signals, there are many things that will affect this. That is, essentially, the time it takes for the signal to travel from sender to receiver. Latency is always the killer when trying to sync two or more devices together. However, there are a few minor hitches in this that need to be understood. These are highly stable clocks that were originally calibrated with UTC, so the signals that originate from them can be considered a good sync link back to UTC, and therefore a good source of synchronization on their own. The GPS satellites each contain three Stratum One cesium atomic clocks in them. It's the Time & Date information that matters here. The NMEA 0183 standard sentences allow the GPS receiver to send information related to Time & Date, Geographic Position - Latitude/Longitude, and individual satellite information. The data in those sentences are defined by the NMEA 0183 (National Marine Electronics Association standard 0183) or NMEA 2000.

The data that is sent from the GPS receiver is a series of standard 'sentences' that contain defined data.

However, they can be used as a crude substitute in the field if one has the necessary software and is aware of the limits. Consumer GPS receivers that are used primarily for navigation or geolocation functions are not designed to provide time synchronization.
