Yes, GPS satellite clocks are corrected for time dilation effects caused by general relativity. The satellites experience time dilation due to their speed and the weaker gravitational field in space, which if left uncorrected, would result in inaccuracies in GPS signals. The corrections ensure the accurate synchronization of clocks on satellites with those on Earth.
They wouldn't have had to depend on the stars for navigation. If the sky were cloudy, they wouldn't have been able to use a sextant. GPS and accurate maps would help them avoid obstacles.
The three-letter abbreviation for the satellite device that TopoFusion software interacts with and uses is GPS, which stands for Global Positioning System. GPS is a network of satellites that orbit the Earth and provide geolocation and time information to GPS receivers, enabling accurate positioning and navigation.
Navigation satellites move around Earth at an altitude of about 1,243 miles to 22, 223 miles and at about the same speed of rotation. These satellites are in what is called Medium-Earth orbits (MEO).
While GPS is helpful it is not the most important invention of all time. Some would say computers are the most important invention of all time. However what powers both of these things? Electricity seems to be the most important invention of all time.
Most GPS units are accurate to within a few metres ( 10-20 ).
It depends on the accuracy of your GPS. An accurate GPS can give you the exact coordinates of your location in the world. For the most part, the higher the cost of a GPS, the more accurate it is.
The Garmin Forerunner 405 GPS are an accurate brand of GPS and a good watch.
The GPS is incredibly accurate. The GPS uses Google Maps and MapQuest. If you are concerned about the GPS, download the Google Maps app to get turn by turn directions.
The military has gps technology accurate to approximately 1 millimeter. conventional gps units (like the one in your car) are accurate to about 15 feet.
Car GPS systems are highly accurate providing there is no road construction or detours since you last updated/Synced the device to the servers. Most GPS have automatic updating or even streaming updating which makes arriving at the wrong destination unlikely.
Most GPS devices are accurate to within 10-15 feet (3-15 meters) of a target and will be this accurate about 95% of the time. This can change depending on whether the GPS has a clear view of the sky and is able to triangulate properly between satellites.
I would not recommend buying a Polar GPS watch as an alternative to your typical GPS systems. While the Polar GPS is accurate for runners it is not accurate enough for a vehicle.
GPS on phones are very accurate. They work just as good as a regular car GPS because they both work off of a satelite that feeds them information.
It depends where and how often the device downloads the GPS information. Streets and roads are always changing, so the GPS device must download updates to be accurate.
GPS technology has progressed a lot in the last few years. You can rely on your GPS to provide your vehicle's accurate location, including your latitude/longitude coordinates.
A watch GPS is just as accurate as a regular dash mounted automotive GPS. They have been able to consolidate the same technology into very small packages, so there is no loss of accuracy.
