The first satellites of the GPS system went into orbit in 1978, and in 1993 a public version of the second generation of the global positioning system was announced. Now we know the release date of the third version of the navigation and features of the new standard, the chips of which will be the high accuracy of the coordinates and the universal frequency available to smartphones in different regions of the world.
Today, the navigation system is provided by 32 satellites, which are periodically replaced by new ones - their maximum service life is 7.5 years. The positioning accuracy of the current generation of GPS IIF is 5-10 meters, but GPS III promises to surpass the "old man" on this indicator.
The new technology will operate on the civilian frequency L1C, which is compatible with the European Galileo, Chinese Beidou and Japanese QZSS - that is, navigation will become universal for most smartphones. By 2023, Raytheon plans to complete the construction of a new generation of GPS operational control Systems to provide services to the military, which will receive navigation with a more secure signal, the stability of which will grow eight times relative to the current standard.
In the near future, the US Department of Defense plans to launch 9 new satellites with a life expectancy of about 15 years, which can detect objects equipped with GPS modules with an error of not more than 1-3 meters. In addition, the third-generation navigation system can be used even indoors.
The first GPS III Vespucci satellite was launched last December. A month ago, the launch of the second satellite called “Magellan” took place. The third will go into orbit in January 2020 using the SpaceX Falcon 9 booster rocket.
A brand new GPS can be expected in four years. The next item on the GPS roadmap will be the IIIF standard as part of a digital search and rescue system with a dual-band signal and a number of improvements for the military industry.
