@skywalker you can read this:http://fellrnr.com/wiki/GPS_Accuracy
gives you a good starting point about GPS Accuracy. Showing a smooth route has it's downsites, because this is not done cause of better GPS Signal it's done with post process only. It's not really possible to get the current speed with GPS (not at all when walking, works somehow when running fast, work's good on biking).
Leikr already applies quite much smoothing, they changed that a lot during software update. I'm somehow even more unhappy with that because they also use WAAS (http://en.wikipedia.org/wiki/Wide_Area_ ... ion_System
) quite excessive which leeds to real problems when doing mountain related sports, because after correcting the elevation with the GPS Points it's really bad if you track looks smooth but is of by 50 meters because then your up or down the mountain
. So when I do mountain sports i do the following: From time to time I stop the activity change the sport to "indoor running", wait for a few seconds and set it back to hiking (or running). Than the WAAS correction is reset and the GPS is spot on again.
The distance calculation should be smoothed but not the GPS Points, I would like this more.
@Leikr Team: Please provide a sport profile (e.g. Hiking, Mountain Bike) where the height is visible, i really need this!
