GPS not accurate anymore.

Adam G
over 5 years ago

I've had my Venu for about 3 months, and GPS has always been accurate to within a few meters up until late December. Suddenly now I'm getting wonky GPS measurements on all of my runs, which is very irritating as it throws everything off.

For example: here's one from a 4.5 mile run that was so off the mark that it recorded me doing more than 5 miles:

Now here's one from early December where I ran 3 miles, and it kept the laps tight and tracked it right on the money:

Most of my runs have been a lot closer to the 2nd one. Every once in a while it might be a little off, but nothing to the degree that it has been over the past couple of weeks. I haven't made any changes to anything. Anyone have any ideas?

    Connect your watch to a computer then delete REMOTESW folder. This contains the satellite data, which possibly could be the issue.

    From a PC:

    • Click Window's start button
    • Click (My) Computer (This PC on Windows 8 or 10)
    • Double-click Garmin device drive
    • Double-click Garmin folder
    • Delete the REMOTESW folder
    • Right-click on Garmin device drive
    • Select Eject
    • Unplug device from computer
    • Sync your device with Garmin Express or Garmin Connect Mobile

    A new REMOTESW folder will get created and an epo.bin file within.

    Also, are you using GPS, GLONASS, Galileo, or some combination of those?

    Thanks, I will try this when I get home tonight.  

    It looks like it is set to use GPS+GLONASS.  Is this sub-optimal?

    In my experience and location GPS alone (left) has better results than GPS+GLONASS (right)

    Well, no luck. I deleted the folder and switched to just GPS, and the mileage was still way off.

    You might be in a zone where the military is messing with the GPS.  later this month much of the Southeast US will be affected from time to time over the course of a week.

    Just thought I would mention that for whatever reason my GPS is back to being dead-on accurate. I don't think it was the updates because I still had problems afterwards, but I've done several runs since the middle of last week that have been right on the money.

    Maybe the satellites were having issues in your area.Thinking
