How well does the GPS work indoors?
- geerlingguy 1y agoI've been testing various GPS/GNSS antennas indoors for the past year, and unless you're in a multistory building or have a full metal roof, there's a good chance you'll pick up 4+ satellites, good enough for a decent time. But it can come and go, especially as there are other sources of interference in the 1-1.5 GHz range indoors, and reflections off various surfaces and objects make the signal way harder to distinguish. But for by far the best chance of success, you should have the antenna outside, ideally with a clear view of most of the sky. If inside, you could put it near a window or exterior wall, but a lot of modern construction materials can block things pretty badly.
- petee 1y agoI have an older garmin gps18x I use for ntp and it gets fantastic reception from a window shaded by trees. I wanted to test a monitor script so I stuffed it in a metal can, capped with a thick plate, and used excessive tinfoil to seal...If i recall it only dropped 2 satellites near the horizon, leaving 4+ with good signal. I suspect the signal was leaking in through the cable. During past year running i don't believe its lost 3d fix once (not in the can)
