The United States can disconnect Russia from GPS
The head of the Russian space agency claims that the United States can disconnect Russia from the satellite navigation system. He did not specify how to implement this technique.
Washington is considering disconnecting Russia from the American GPS satellite navigation system. At least this is stated by the director of Roscosmos – this is reported by the Russian media.
You know that today, as part of the sanctions, the United States is considering disconnecting the Russian Federation from GPS. Do you know about this? You don’t know. And I can tell you that such an issue is being considered,
Rogozin said.
According to Rogozin, there is nothing to worry about, since “every smartphone is also connected to the Russian GLONASS system.”
A little bit about GLONASS
Russian GLONASS has become a kind of showcase of Russia’s struggle with technological sanctions imposed by the United States and the European Union. They tried to transfer the satellites assembled from foreign parts to the Russian element base.
However, the reality was not so brilliant. Currently, 25 of the 27 GLONASS satellites in orbit (of which 22 are operating for their intended purpose) are second-generation Glonass-M spacecraft. Their production has long been discontinued, but in recent years the Reserve stored on the ground has made it possible to quickly replace disabled devices.
The accuracy of determining coordinates using Glonass today is 1.2 meters with ideal weather. For GPS, this indicator is 70 cm, for the European Galileo system – 50 cm. However, in practice, everything is not so accurate. The atmosphere degrades the signal from the satellite by at least 2 times, so in fact, the accuracy of GLONASS is somewhere in the region of 2.5 meters, but such indicators can only be seen in an open field. In normal urban conditions, the navigation signal gives an even greater error of 5-10 meters.
Now the last Glonass-M is left on Earth, while there are many more potential candidates for replacement: of the satellites currently operating, 13 are already outside the seven-year warranty period of active operation.
This certainly affects the grouping status and navigation signal parameters. Right now, Glonass has 22 devices operating, although there should be 24.
