From what I have been studying, there is very little outside of solar flares and such which will interfere with GPS signal. But there are PLENTY of things which produce EMI, or electromagnetic interference, such as current running through high tension wires. EMI produced by an EMF (electro magnetic field) can interfere with your compass. So can large metal structures such as towers, cell phone towers, building with a lot of steel in them, etc. If there is a problem with your compass reading such as an error induced by EMI, you are done, because the Phantom navigates using GPS and compass reading in conjunction. If your compass reading is bad, bad things can happen. |
