Most accurate is probably a cell phone for an Asian market. It'll have a GPS chip that will receive from the non-US constellations. The Russians, Chinese and the EU all have their own GPS birds now. Typically the US market phones only receive US and Russian constellations.
US constellation isn't super accurate over North America for obvious reasons.
WHAT? Are you off your meds? The US GPS is SUPER accurate. My Google Maps app actually shows me in the correct RV space here in Houston. Your post is nonsense.
Cell phone provided Google maps get their feed and your location via triangulation through the provider cell sites.
GPS are direct from earth roaming satellites, thus, Global Positioning Satellites.
No, that hasn't been the case for years.
Every cell phone you buy has a GPS built in and Google Maps will happily use the satilite system (you can't turn it off and Google Maps has to have permissions). It can refine the accuracy using cell towers but really, unless you are doing survey work, the accuracy is plenty good enough and will work fine even away from cell towers. The only downside is starting a route outside of cell service but you can download map areas and really getting outside cell coverage is getting increasingly rare.
You can also download offline mapping applications (many for free) that need no cell coverage once loaded.
We have an old Nuvi but when it dies, we will switch to the cell phone. Mostly still using it because it has lots of personal destinations already programmed and too lazy to transfer them.
Live traffic conditions and incident notifications on Google maps is great. Usually if looking for a gas station or restaurant, have the wife pull it up on her phone.
