After the upgrade the GPS accuracy will be 60-90 cm
the GPS System consists of 24 satellites, and they are already in orbit for quite a long time (was launched from 1990 to 1997). It's time for an upgrade. In the near future all devices standard current GPS will be replaced by a newer version of GPS IIF, which has a number of advantages, including they are more resistant to jamming (now you need jammers to 100 times more powerful).
But most importantly, GPS IIF provides a much higher positioning accuracy. If the current satellites provide the accuracy of 6 meters, the new satellites will be able to determine the location, as expected, with an accuracy of no more than 60-90 cm. If such precision is not only for military but also for civilian applications, it is good news for Foursquare users and owners of GPS-navigators.
Moreover, such improved accuracy of GPS means that it is possible to use satellite coordinates to program applications of a new class, such as augmented reality.
At the moment in orbit, only one is satellite GPS IIF SV-1, which is fully connected from 27 August 2010. The second satellite, SV-2 launch this year.
The original contract was for the launch of the 33 GPS satellites of the new generation, but then due to technical problems the start of the launch was postponed from 2006 to 2010, and the number of satellites was reduced from 33 to 12. They will all be launched into orbit in the near future.
Improved accuracy of GPS satellites of the new generation became possible thanks to the use of a more accurate atomic clock. Since the satellites move at the speed of about 14,000 km/h, improving the accuracy of time even in the sixth sign is critical to triangulation.
