In light of the recent events today where Google has had to restrict its dealings with the chinese company Huawei for "security reasons". Is it feasible for the american administration to stop Chinese devices making use of the GPS network and stop the Chinese chartplotters from working?
 
GPS is a listen only system, with a massive install base worldwide, so any changes would render all GPS systems obsolete and not just the chinese ones. They could turn on selective availability in a geographical area, like over China, but it is relatively easy to counter with correction signals sent over RF. Like LAAS.

Strangely enough, to sell a GPS system in China, there are a slew of restrictions ...

Yes that makes sense. I've also read that the Chinese are developing their own system which should be available world wide by next year.
 
GLONASS is in operation I sure the Russians dont mind sharing and the European Galileo is up and running , we dont mind HUAWEI the ministry of Defence have a contract for their cell phones :p
 
Yep, it's called BeiDou (BeiDou-3 is the current version). There is also the Russian GLONASS, Europes Galileo and the Japanese have QZSS ...

The russians insist systems sold in Russia use GLONASS, the Chinese are very restrictive on mapping and E-Call software, providing State_Certified software that has to be integrated into systems sold in cars in China.

You can buy chips from ST that do everything in one package ... GPS, GLONASS, BeiDou, Galileo, QZSS .... so even if the americans did something to GPS, there are other alternatives.

Google spies on all of us and probably has a back door for the use of the CIA and GCHQ so why worry.

During the Cold War, the USSR deliberately distorted published maps of the Soviet Union. Of course, once spy satellites and Landsat were up, this was pretty useless; it made life (more) difficult for the average Russian, and if anything drew attention to things they were trying to hide! That said, I've had dealings with Soviet cartography of Antarctica, and the average newspaper is printed on better quality paper than they used.

On a school trip to Russia in 1971, we were solemnly told that it was illegal to take photographs of ANY transport installation, or to take photos from trains! I don't think it stopped us...

However, more recently (1983), we were forbidden from taking photographs of the Norwegian airport at Bodo.
