Can I legally use a GNSS device in China?
According to Hvistendal (2013), Science:
Since at least 2007, it has been effectively illegal for foreigners to operate a GPS device in China. International brands of cameras with GPS capabilities have been rigged to avoid displaying coordinates if the user is in China, says Stefan Geens, an analyst in Stockholm who studies networked digital maps and geospatial imagery.
On Quora, different answers contradict each other, but at least one confirms the GPS-enabled camera rigging.
I usually carry a handheld Garmin GNSS device around, which includes the ability to receive GPS signals. I have offline Openstreetmap data downloaded on the device. If I do so in China, will I risk getting this device confiscated upon entry, or arrested for illegally using GPS? I suspect that if GPS devices are illegal, then that also applies to GLONASS and Galileo (unless GPS is banned for being American...). Does it?
