Chinese GPS System To Be Offered Free
MattSparkes writes, "The Chinese GPS system, Beidou, is apparently to be opened up for free access within China, worrying European investors on the €2.5 billion competing project, Galileo. Initially, China had declared that access to their system would be restricted to the military, and Europe had planned to recoup some of the cost of their system by selling licenses to China. Michael Shaw, from the US government's National Space-based Positioning, Navigation and Timing Coordination Office in Washington DC, said, 'Frankly, China's behavior towards Europe is not so different to how Europe behaved with us when GPS was the only game in town a decade ago.'"
Each of their citizens will get a free tracking device implanted inside them. What a great country!!
Aren't they afraid of how all those people are going react when they find out they live in China?
The Chinese are taking power away from corporations and giving it to their people, by making public services available for free. That is almost the opposite of what happens in the West.
I'll probably be modded down for this...
The economic benefit of free location services is so great, it makes sense for a country to provide this the same way as it provides a national highway system.
Furthermore, it'd simply be absurd to make your businesses pay all the costs to field a system they aren't allowed to use, and have them pay fees to get similar service from a foreign country. Such a policy would serve neither security nor economic interests. I'm all for private development of technologies, but I can't feel too badly for Galileo investors if they were counting on China to act in such an irrational way.
The resolution of the Chinese system isn't so great, so clearly there's a business opportunity for the private sector there to create subscription services, either to a competing system or to some kind of terrestially based correction service.

Seriously, how many different navigation systems do we need?
Let's see, the U.S. has GPS. And the Europeans don't trust Americans, so they want Galileo. And the Russians don't want to admit that the Europeans could be better than them at anything, so they're keeping GLONASS around. The Chinese don't trust anybody, and nobody trusts the Chinese, so they have Beidou. The only thing we're missing is one by India (to compete with the Chinese), or maybe one just by France that's purposely incompatible with the rest of Europe's (is "SENAV" taken?).
How soon until the satellites start running into each other? (Yes, I know they won't really; it'll probably be radio spectrum that we run out of first.)
At least as it looks right now, the only system that's even going to be an improvement over GPS is Galileo, and even then it won't be by much. Seems like it would be a whole lot more productive to build systems that augment the signal already available from GPS, and then can call back to providing position itself if GPS goes out; then you'd be able to get higher precision. With higher precision signals, a whole lot of interesting things become possible: you can have automatic self-driving farm equipment (like John Deere's ground-based StarFire augmentation system), lower-cost aircraft navigation, all sorts of cool remote-sensing applications. If you thought that GPS in itself was cool, there are far more opportunities to use it, when you start talking about inch-accurate systems.
The duplication of effort seems mostly like a penis-length contest, and while I think competition in all things is generally good, I'm not sure that this is really happening for any rational reason. There are better uses that the investment and satellite space could be put towards, than simply overlapping each other's navigation systems.
"Ladies and gentlemen, my killbot features Lotus Notes and a machine gun. It is the finest available."
It seems to me that if you had a GPS device that could understand signals from all of the systems you would have a large increase in precision. Each system says you are at point A +/- some distance (effectively a circle with point A in the middle). Unless point A is EXACTLY the same for each system, and I can't imagine it would be, then you get three overlapping circles. You now know that you can only be in the area where the three circles overlap. Any area outside of the overlap is now known to be wrong. Am I right?
Kind thoughts do not change the world
Inside joke. The Chinese word for compass is "south pointing device". Thats because they first used it for geomancy, where "good energy" comes from the south. The Vikings and other Europeans used the compass as a navigational aid for when the north star was occluded, so the European compass points north.
