The GPS Wars Have Begun (techcrunch.com)
Where are you? That's not just a metaphysical question, but increasingly a geopolitical challenge that is putting tech giants like Apple and Alphabet in a tough position. From a report: Countries around the world, including China, Japan, India and the United Kingdom plus the European Union are exploring, testing and deploying satellites to build out their own positioning capabilities. That's a massive change for the United States, which for decades has had a practical monopoly on determining the location of objects through its Global Positioning System (GPS), a military service of the Air Force built during the Cold War that has allowed commercial uses since mid-2000 (for a short history of GPS, check out this article, or for the comprehensive history, here's the book-length treatment).
Owning GPS has a number of advantages, but the first and most important is that global military and commercial users depend on this service of the U.S. government, putting location targeting ultimately at the mercy of the Pentagon. The development of the technology and the deployment of positioning satellites also provides a spillover advantage for the space industry. Today, the only global alternative to that system is Russia's GLONASS, which reached full global coverage a couple of years ago following an aggressive program by Russian president Vladimir Putin to rebuild it after it had degraded following the break-up of the Soviet Union. Now, a number of other countries want to reduce their dependency on the U.S. and get those economic benefits. Perhaps no where is that more obvious than with China, which has made building out a global alternative to GPS a top national priority. Its Beidou navigation system has been slowly building up since 2000, mostly focused on providing service in Asia.

The US GPS, Chinese Beidou and Russian GLONASS are all positioning systems intended primarily for military use but which offer a degraded lower-accuracy signal for commercial and private users. The EU's Galileo navigation system offers precision to within a few cms, effectively military-grade accuracy, to paying commercial users as well as open but less-accurate position data similar to the "free" GPS, GLONASS and Beidou systems.
Thanks for crediting us here in the UK with Galileo, but it's an EU project, not a UK one, and we appear to be shut out of it because of Brexit.

There are a few of issues.
When it was just GPS it was easier to jam/spoof. Now we can compare data from multiple systems to detect spoofing. Other services can provide greater precision than the US wishes civilians to have, or remove other restrictions like the maximum altitude and speed limits.
It's a good thing.

Uh, what? Yes, the UK does net pay into the EU, as one would expect from one of its richer countries. Germany however, has a net contribution over twice that of the UK (larger as a share of its economy, too). France, too, gives more. This is largely due to the fact that the UK gets two-thirds of its net contribution back as a special rebate. In fact, if you look at net contribution as a share of the national economy, the UK comes in ninth.
