Resolution of less than 1 meter is normal with a decent view of the sky and a lack of interference. GPS itself is always receive-only on our end as consumers.

What problem are we trying to solve here? At this point in time, guided navigation with completely offline maps and GPS has already been a no-brainer off-the-shelf thing for decades.

AFAIK it's almost always enhanced by things cell tower data, wifi network data, and external data sources (besides the satellites). Look up GPS/GNSS enhancement and augmentation for the latter.

		I mean exactly what I wrote: "GPS itself" means GPS, itself. Not GPS and WAAS. Not GPS and RTK. Not GPS + wifi + BT + cellular. I didn't mean any of those things, so I did not write any of those things. If the thing is more than GPS -- by itself -- then that's outside the scope of what I was referring to with the juxtaposition of the words "GPS" and "itself". (If a thing -- by itself -- can be better specified to be that way using concise phrasing, then I'm all ears.)
