btstack - issue #102

BTStack GPS location accuracy based on satellites


Posted on Nov 26, 2010 by Grumpy Bird

This is more of s feature request but the location accuracy registered with the system ( eg how big of a blue ring is around the dot) should be based on how many satellites you have or something. It would be useful for me.

thanks for the request. can you come up with a formula how to convert nr of satellites into size of blue ring in meters :) ?

I honestly wouldn't care if it was accurate. I'd just estimate based on a average. Like 3-4 satellites 10-8 meters (that's how some other phones like android do it). 5-6 satellites 5-8 meters. 7-8 satellites 3 meters. Anything above that could be 1 meter. That's just an example I made up using what I've seen on Android phones. I don't think they actually know what the accuracy is they just guess based on satellites and maybe other factors. It would be useful to me so I don't have to flip back to btstack gps to see satellites .

Roqybt4 does this. I don't see why btstack couldn't.

the 1.6 release uses "accuracy" = HDOP * 10m (as suggested by the Harald Schlangmann, the author of Harry's LapTimer).
