Can I use a M7 GX for primary navigation? |
No. No radio link is 100% reliable, the M7 GX should not be used as the primary source of navigation or location information.
GPS used in urban environments can suffer from "shadowing" caused by
tall buildings, signs, and even large vehicles (anything that
interferes with the line-of-sight between the receiver and the
satellites to which it is initialized), and also an increased risk of
multipath errors caused by glass, steel, and neon sign reflection.
