Do you know what a GPS is and what GPS stands for? Most people do but for those of you that don't GPS is short for Global Positioning System and a GPS is a satellite navigation device that's space-based and provides information about location and time in any set of weather conditions, in any part of the world, as long as there aren't any obstructed sightlines in front of at least four GPS satellites.
Most people are familiar with GPS systems that are found in cars that help drivers navigate their way on the road when they're in need of direction to get from one location to the next. There are however many aspects of a GPS that aren't as well known and we want to cover one such aspect, which is GPS frequency standards.
If you've never heard of GPS frequency standards and want to learn more about GPS frequency standard you're going to want to keep reading the rest of this article. In general terms a frequency standard is an oscillator, which is an electronic circuit in which electronic signals are produced repetitively, that are used for reference or frequency calibration. Most frequency standards are generated through a fundamental frequency that has a high degree of both precision and accuracy, which then provides much needed reference points.
When it comes to a GPS and GPS frequency standards frequency standards are used in GPS systems to calibrate the GPS system and to also synchronize the master clock of the GPS and stay in touch with the GPS device. Without frequency standards a GPS wouldn't be able to function properly, as a GPS needs frequency standards to be able to communicate with satellite systems in order to receive the proper information that allows it to function normally.
In the world of GPS systems there are different GPS standards that each have their own unique reason to exist and those GPS standards include ED50, ETRS89, GRS 80, NAD83, NAVD88, SAD69, SRID, UTM, and WGS84. A GPS wouldn't function properly if it wasn't for frequency standards, as a GPS can't calculate its position unless the signals sent to the GPS are timed precisely and that's what a GPS frequency standard is there to help with. Messages transmitted to GPS devices need to have the time of the message and the satellite position of the message and GPS frequency standards play a part in that occurring.
