Inaccurate gps tracking after update 12.23 on FR 955

Hi guys!

After update 12.23 gps track has been disappointingly inaccurate.

Before update gps track was incredibly smooth!

What do you think?

Maybe opaque autumn clouds?

    Does anybody know how long it usually takes for a new FW to be released? Like is it a scheduled thing or would they be looking to push one out asap given the issues shown? I'm looking to upgrade to a 955 but these threads have seriously put me off making the move imminently (but hoping things improve going forward)

    My uninformed guess is that we're not going to see the next firmware update until the end of this month.

    I have performed full device reset.

    There is no any significant changes.

    All,

    After reviewing the information provided (in this thread and via email) by many of you, I am having a difficult time finding examples of when the watch is recording a GPS position outside of the 3 meter range of accuracy mentioned in (the "What is GPS Drift?" section of) our FAQ below:

    What Can Cause GPS Accuracy Issues on My Fitness Device?

    If you have an example of an activity that shows an obvious inaccurate GPS outside of the 3 meter range, please provide the following:

    • Have you changed the Data Recording setting at all? (i.e. from Smart to Every second)
    • URL from Garmin Connect Web for the activity recorded on 12.23 software
    • URL from Garmin Connect Web for an activity with the same route that was recorded on 11.12 but did not have the poor GPS data
    • Screenshot (from the Garmin Connect app or Garmin Connect Web) of the GPS track of the 12.23 activity
    • Screenshot (from the Garmin Connect app or Garmin Connect Web) of the GPS track of the 11.12 activity
    • Time during the activity where the inaccurate data was recorded (ex. "between 16:30 and 17:15 minutes into the activity", NOT "the entire activity is inaccurate")
    • Confirm that you grant consent for us to access/view your Garmin Connect account

    I do see that some of the examples provided include GPS tracks that are not necessarily as smooth as the pre-12.23 examples.  This added information that I have requested will help us investigate these differences.

    Sorry, but I sent two very specific cases where the route marking was completely wrong, including the routes of other people who were with me and had the correct markings with much older devices. If you need more information, I am available and have my permission to access my account data.

    in the examples that you sent, the GPS tracks for the activities look nearly identical, though I do see a discrepancy in distance.  I should add that one of the activities was 20 minutes shorter than the other, so that needs to be considered as well.  If you would consider providing all of the information requested above in my last comment, I'd be happy to continue working on this.

    exactly! Garmin-Kevin is right. you need to check the GPS connection frequency setting. after firmware 12.23, the parameter turned on Intelligently. You need to set Every second. I set Every second and everything became OK as on 11.2 firmware.

    One reason you always find near-perfect traces of submitted routes could be that Garmin Connect “corrects” the drawing to make it look error-free. Observe these prints of the same activity I sent you, the first ones from Garmin Connect the last ones from the same points, from the same activity, taken from the STRYD app.
