Wait...I'm confused...<div><br></div><div>enablehighaccuracy with a timeout set to earlier will get the high accuracy coords and get you the speed you want because it will use a cached location and not fire up the gps on the device, but it will give you the accuracy you want. If you're not using it as set to true, you're doing geoloc based on cell towers or ip...</div>
<div><br></div><div>as for what you use to get the coords, I'm using the same thing, aren't I? or am I missing something else here...</div><div><br></div><div>thanks for the link, here's one I found useful.</div>

However, I rather do the GPS, since this is native app (hybrid app -<br>
Xcode and JS) and use<br>
<br>
position.coords.latitude<br>
position.coords.longitude<br>
<br>
See the advantage here:<br>
