    Ambit2 vs Ambit GPS smoothing

    Certainly there is a new algorythm:

    Same settings on both. Stopped for about 1 min, kept both running.

    Two questions:
    1. Please define the colors as Ambit 1 or 2
    2. Which is more accurate (did you do that little circle move on the yellow line)?

    Thanks

    Auto pause off. (but I know where you are coming from ....looks like this is how it should work!)
    Stationary waiting for running companion.
    Ambit is Yellow.

    Wait, you have access to the Ambit 2?

    Which version?
    We want pics! We want pics!

    This new Ambit 2 is supposed to have a new revision of the SIRFIV that is version 2.2. I wonder what have been improved in that version. Perhaps it have better CPU to calculate better ephermis data.

    Can you try try walking along the street and see if the issue with wiggly lines during walking speeds have been fixed?

    Pics here

    I will try walking but certainly smoother with running.

    Could you please clarify a bit: so you actually did the circle (walked?) but Ambit2 detected it was not done running so it was smoothed off, right? If the exercise mode was 'walking' then the circle would be there - or what is it that's happening there?

    BTW, does the gps still cut corners at crossroads at high speeds? The corner cutting is resulting in too short overall distances on the first Ambit. I wonder if the improved algorithm has some way to deal with this.

    Re: Ambit2 vs Ambit GPS smoothing

    OK a bit more running to be done to test properly
    Ambit yellow R wrist, Ambit2 orange L wrist

    Summary to date: fewer samples with Ambit2 despite 1 sec recording resulting in smoother tracks but less detail with quickly changing tracks.

    Tomorrow's run I will wear both on the same wrist just to try and eliminate any discrepancy.

    Thanks for the pics! What kind of a real life effect does the smoothing have on overall distance? Naturally a bit shorter but by how much on various distances?

    Re: Ambit2 vs Ambit GPS smoothing

    10.34Km for Ambit2, 10.40 for Ambit BUT I was messing around with changing Ambit2 back and forth from 1 sec to 60 sec modes on some other areas of the run with obvious effects. As I said I will do a trailrun with exactly same settings and on same wrist and report back.
