This seems like a great step. I had no idea the accuracy was only 5 meters right now. My phone feels like it is more accurate than (like 2 meters) that but I suppose that is because software does a good job at guessing where you actually are? It's awesome that it is half the power of current chips too. Because I think smart phone users care more about battery life than accuracy. Edit: Changed my messages because I re…
As an avid hiker and runner I'm more excited to see what this will do for things like Garmin smart watches. I run through downtown Boston a few times a week and the accuracy is very bad at times making you look like you run much farther than you do.
I've run into a severe issue with Fitbit's app on the iPhone 7. On my older iPhone, the mile counts were reasonably accurate. On the 7, there's a spurious ~2 miles per hour added at all times. My guess is that the 7's chip updates position much more frequently, so that small inaccuracies (a couple dozen feet west, then a couple dozen feet east on the next update) make it look like I'm sprinting all over the place in…
If the terrain forced you to take a lot of shorter steps then that explains it. In 6 hours of normal steps you'd expect to walk about 18 miles.

If you are interested in improved speed & distance tracking, take a look at this: http://fellrnr.com/wiki/GPS_Accuracy There are some foot pods that will outperform GPS.
All current running watches and phone software uses single point calibrations. Now if they curved fit 2 or 3 points....

> to prevent bad guys from using them in missiles and other nasty stuff I was confused. So here's a translation: Bad guys = US enemies or non-allies. Not bad guys in any moral sense.
More like parties that are not technologically advanced nation states. Russia has its own satellites, China will find 10 ways around the problem, but a few random dudes won't be able to DIY a cruise missile with cheap parts that would be precise enough to be dangerous. Or at least that's how I always understood it.
>will give the next generation of smartphones 30-centimeter accuracy instead of today’s 5-meters Didn't the US scramble the civilian signals specifically so it wouldn't be too accurate? And they're just okay with civilians having access to ultra accurate GPS receivers?
Why would consumers want this type of accuracy ?

Do you run the same path frequently? When I do, I keep the path the same, as I pre-calculate the distance, and can keep a watch to track my time. Thus I have no need for path tracking. A GPS unit is useful for assisting dynamically changing routes (e.g. driving) or to track unknown paths (e.g. plotting your hike in snow/darkness). May I ask what you'd need a fine-accuracy GPS unit for during a run?

When moving slowly (walking).
When precise coordinates are needed (self driving vehicles).
When precise altitude is needed (airplanes and drones).
When tracking smallish things on a person (head tracking for augmented reality).
When performing certain scientific measurements (continental drift).
Finally, so that when I'm sitting at a stop light my navigation doesn't freak out and suddenly think I'm moving in the opposite direction.
I'm sure there are tons more.
I wonder if we'll see these in Microsoft's 2018 HoloLens. 1ft accuracy + spatial mapping = a global spatial mesh with countless commercial applications.

Things have changed since the 90s. > In May 2000, at the direction of President Bill Clinton, the U.S. government ended its use of Selective Availability in order to make GPS more responsive to civil and commercial users worldwide. > The United States has no intent to ever use Selective Availability again. The military has better precision, only because they buy better hardware. Similar hardware is used in commercial…
