It's mostly airports that we need to worry about, and they don't tend to change much. Sure, TMA boundaries might vary occasionally, but that's not really much of a worry, because most drones won't be up at 1000+ ft.
- amelius 11y agoWhat about its weight?
- EdHominem 11y agoMore importantly, what failure modes does it have? Do you have to have GPS lock to takeoff? What if you lose it while flying? At DEFCON someone demonstrated dropping drones from the sky by spoofing GPS coordinates to inside an airport. Funny, but it guarantees I won't be buying one of them because of the potential for harm to my camera, etc.
- cpncrunch 11y agoI don't know, but Phantom have been doing it for years, so you could see how they do it.

- thescriptkiddie 11y agoI haven't had good luck with style of GPS module on my models, even a <100 mW 5.8 GHz FPV transmitter tends to swamp the GPS signal to the point where getting a lock is impossible. They're also prohibitively heavy on smaller models. A 10% increase in mass (for a 300g quadrotor) can shave an entire minute off of your run time.

- MertsA 11y agoThat's just the antenna. Also, you can't get an actual GPS receiver for under a $1, around $10 is a bit more reasonable for a low price.
