- wmf 6y agoIt depends on the orbit. AFAIK GPS, GLONASS, and Galileo have global coverage (my phone can see all of them in the US).
- jburgess777 6y agoThe Chinese system is BeiDou. If Wikipedia is to be believed, they will only achieve global coverage in 2020. https://en.wikipedia.org/wiki/BeiDou https://en.wikipedia.org/wiki/BeiDou
- yumraj 6y agoThat is not my point. It can be Geo limited by the OS. If !(in China) _disable_ Although even that will cause unnecessary headache for hardware and OS vendors and will/might still lead to new security issues and backdoors.
- nix23 6y agoProblem is...you (the chip-maker) pay licenses to the satellite-owners, if your chip does not work outside china, no money. The Chinese 'GPS' is probably just for military or for the independence from other systems.
- yumraj 6y agoYes, but hardware vendors need to decide if they put the chip in all devices and reduce manufacturing/design/testing costs, or put the chip on a Geo specific model and incur higher mfg/design/testing costs. It's always a tradeoff and the cost of the chip in itself is not the sole decision driver.
- tialaramex 6y agoThese headaches presumably are from the dizziness induced by introducing location checks inside the location determining code.
