What I don't understand about this GPS spamming: we don't need to rely on GPS. We have Galileo, (GLONASS) and BAIDU. That is the reason we its now called GNSS.
Most of the chips and as such the receivers are supoorting all of these systems in parallel. While I understand that the Chinese use their own coordinate system, I don't if BAIDU is based on that or not. Galileo is available. Galileo is able to use authenticated signals. Galileo has much improved over GPS. I assume in (important) comercial applications like aircrafts, you could use the better Galileo service for which you have to pay for.

So how important is GPS spaming really?
