HPL announced at Verizon.

I don't want anyone knowing my exact 1-2cm! That is a feature I can hopefully avoid. Hopefully it's NOT standard with new phones until after I am dead.

Seriously in my opinion this should only be enabled remotely used by law enforcement only with a warrant to find missing children (who would be likely carrying a cell phone) or those on the wanted list dumb enough to be carrying a cell phone.

Personally I don't care if Garmin does or doesn't add that feature. What's the point if I'm navigating six miles or 600 miles and my Garmin GPS can get me to within 2 cm of my destination? It'd be impressive, but as far as I'm concerned, anything within twenty-five feet or so is close enough for me.

this being handy for surveyors who want 2cm accuracy in a handheld GPS but for automotive use, it's overkill.

That degree of accuracy will be needed for driverless cars. Trouble is that the maps are not that accurate.. yet.

This technology might be useful for military targeting.

Since this is only in 100 major cities, it would lead me to believe that it's getting that precise a location from triangulating cell towers and not from satellites. A 2-way cellular communication would have to exist and current Garmins don't have that.

I would like to play around with it, but I agree that in the grand scheme of things, for most people, most of the time, it won't matter.

Similarly, the cell phone providers are adding 5G gear. And, that is fine. Personally, I don't need to be the first in my neighborhood to have a 5G smartphone or pay more for 5G service. Now, when it is time to buy a new smartphone, THEN I will look at getting it, but not so much as a burning need for it.

It sure would take the search activity (bumblebee dance) out of Geocaching. Seems like it would make that game pretty boring if you didn't have to do a search for the last 4 or 5 meters. Of course, the people who hide the caches would also have to use this technology to get that kind of coordinate accuracy.

It appears the popularity of Geocaching has dropped off in recent years. I used to do it while riding my bike but gave it up due to fewer and fewer caches out there.

The increased accuracy would indeed eliminate some of the challenge but many cachers use offsets or purposely distort the location accuracy to increase the difficulty.

Military will definitely be using this if not already using it. Actually I'm surprised military/government would allow this in public domain with all the nut jobs with bad intentions.

Hyper precise location has been built into the GPS constellation for years but the technology was blocked for civilian use. For most purposes, 1 to 2 meters is sufficient. I know I don't need more accuracy than that. Now for surveying, farming and emergency response, the need is there. Farmers and surveyors have had access to hyper location by using third party systems such as those manufactured by Trimble.

That is a bit out-of-date. Selective Availability, oddly enough was actually turned off, not on, during wartime for Desert Storm, as so many of our own soldiers were using civilian GPS receivers we thought they would benefit more than the other side.

Then it got turned back on for a good while (it was running when I got my first Magellan "shoe-box" GPS). But it was turned off for good during the Clinton administration and I believe they actually deleted the supporting hardware from the more recent satellite designs.

Although HPL may indeed be useful for some, it relies on 4G or 5G cellular systems which are available in a relatively small portion of the globe.

IMO, the hyper accuracy would be more useful in rural and remote areas, some of which have no cellular coverage at all let alone 4 & 5G.

Where I live, I fear I won't see 4 or 5G service in my lifetime.

Being that it's only available on 4G and 5G units. It seems to be cell phone based.

Cell phone “stingrays” (phony cell sites used by the police and spies) would then be able to announce a false location to bamboozle the system locally. What would that do to the autonomous car business?

Yea looks like this has nothing to do with GPS but uses cell phone technology.

I think HPL can be very helpful in GPS systems in helping drivers be in the right lane.

Also, EVENTUALLY with advancing technology it might help avoid traffic in specific lanes - like crashes, break downs etc.

HERE tech has a write up about having such technology in the future.

Lane precision on the road can someday be very helpful!

In addition to accurate location information, successful Lane navigation would require considerable enhancement to the maps.

But some people and businesses will. Looking at the Verizon website it appears to be offered with 5G only.
