US carrier gonna sink 2000km away from China off shore.
China satellite navigation starts services to Asia

A Chinese satellite navigation network created to eventually compete with America’s Global Positioning System has started offering services to Asian users outside the country.
The network’s spokesman, Ran Chengqi, said in a press briefing that the Beidou system is offering from Thursday services including positioning, navigation, time and text messaging to users in the Asia-Pacific region.
China expects Beidou to generate a 400 billion yuan (HK$492 billion) annual market for services to the transport, meteorology and telecommunications sectors.
China, and especially its military, has long been wary of relying on the United States’ dominant GPS network, fearing that Washington might take the system offline in a conflict or an emergency.

I don't know if anyone could answer this, But how many satellites has china launched in the last 10 years, and how many would they need to have there own independent network?
The end is coming!!
But really, threat to aircraft carriers that are underway isn't the real problem. Most US forces in the region are still on land or in harbors. GPS significantly improves the missiles' accuracy against fixed targets.
So why don't we make our own too and do the same to China? 8) Sink the Chinese carrier while it's still in port.
Oh god, not the DF-21 "Wunderwaffen" again...
Before one can successfully launch a long range AShM/ASBM, one needs to be able to successfully DETECT and TRACK the target ship(s). You can be sure that in case of all-out war an AWACS or similar aircraft will be shot out of the sky anywhere near a carrier group and same will happen to surveillance/navigation satellites. You can also be sure that military subs/ships/planes will leave their respective bases in case of high DEFCON. So until someone can come up with a sure way to detect and continuously track
surface vessels during war (hasn't happened yet, even with all that Cold War nuisance over the last 60 years) all these ASBMs are "wunderwaffen" on paper only.
Back on topic: Congratulation China, and welcome to the group of nations with similar systems.
LMAO, you think shooting down satellite is easy? Do you even know the altitude of the navigation satellites? How do you found them and shot/ guide warhead to them?
In case you didn't know, here are some numbers:
In 2007 Chinese shot down satellite at altitude under 1.000 km, while navigation satellites like GPS are at 20.000 km, GEO satellites are at 35.000 km, and the radius of the Earth is 6.000 km
The power of Photoshop is a superpower indeed
If the Europeans can't trust the Americans enough and had to build their own Galileo system, then the Chinese should be prudent enough to build their own too.

Now Apple Maps makes total sense. They used the Chinese navigation services.
