Northern Exile 19 Nov 5:20pm, 19 Nov 2024 10,615 posts	0 Northern Exile The avionics side of Garmin is more advanced than you might expect. You must remember too that one of the original goals of GPS was for weapons targeting, thus it's quite capable of delivering the sort of accuracy required for commercial flight. Tomahawk (for example) uses a combination of GPS and inertial navigation to get to its target.

I don't know how confident I'd be on a plane knowing that it's navigating with the same sort of tech that gets me round my local bike ride! The pilot has a choice of either: Delaying take-off while waiting impatiently for his navigation device to lock on to some satellites; Setting off anyway knowing that his flight log will be incomplete but hoping the Nav locks on eventually at some point on the route.

Gotta hope the Tomahawk GPS navigation is more accurate than my watch in built up areas! (Very dark observation is that it might not be according to many of the West's detractors.)

Northern Exile 19 Nov 8:26pm, 19 Nov 2024 10,616 posts	0 Northern Exile Hysterical But, if anyone is genuinely interested in this please consider the following facts: 1. A decent GPS antenna has infinitely more gain than the things in wrist/bike mounted Garmin. 2. Exposure to the GPS/GLONASS constellations is much (much) better when you're at altitude and things like buildings, trees etc aren't obscuring the gaze. 3. GPS for military applications is an order of magnitude more accurate. What the commercial world gets is second-tier.

I'd be giving you a close battle at this point mate, 2 days without my phone & like having my arm cut off !!!!
