GPS Lock and Offset

@stromdiddily
did this happen once or did you notice this behaviour more often?

This is the first time it’s done anything like this but like the title suggests I have issues basically every time I start a run w tracks being in line but offset

@stromdiddily hello, do you mind if you can share some screenshots on your gps tracker

Like this one?

GPS was locked THEN I proceeded to tie my shoes and do my warm up before starting.

It looks like a dick

feel free to include it in your next product review

@stromdiddily no, didn’t happen to me, and it sounds strange that it just started to happen to you now. I guess you already tried with a reboot
If this becomes a constant let us know, with logs and everything. Sony is baking GPS firmwares often recently, and the Vertical will get an update with next firmware release.

Thank you sir. Will shoot you a DM if it doesn’t sort itself out.

Today on the same route, I had absolutely perfect tracks so hopefully just a one off!

This is quite predictable now whenever I run in a new area. First run in Mexico on vacation had pretty significant offset and a long-ish time to acquire signal. First run back home, same deal.

Both times I made sure to sync with the app to get updated AGPS and wait a good 30 seconds or so after GPS signal acquisition to start the activity.

I am willing to bet good money that my run tomorrow from the same location will lock before I can tie my shoes and have no such offset.

@stromdiddily for what it is worth: I had a huge GPS drift last two days here in the neighborhood. I have never seen this in years. Rebooted the watch and hopefully it will be gone next activity.

isazi

No issues for me in the past few days, but next update will also have GPS firmware updates.

@isazi The contours were good, but the whole track was displaced.

@surfboomerang I have only seen that happen with wrong (not as not updated, but wrong) AGPS data.

surfboomerang

@isazi only time I have seen this was indeed with the huge Sony AGPS issue 1-2 years ago. Hopefully the reboot worked for the next activity

Run yesterday had a good 20m offset as youve reported, for first 10 mins.

Fingers crossed!

@stromdiddily This is odd, I travel a reasonable amount and this does not happen to me. For example on my last race I had not used the Vertical in quite some time. I charged it for the race and started off. The last time I used the Vertical was a week before near my home. Here is the beginning of the Race located 800km away from home. I have not seen this when traveling.

That’s what has me thinking there might be something up with mine. Folks are raving about the accuracy and if this was a common occurrence, someone else would have brought it up (5k, dc, etc)

I agree and would wait for the firmware update coming this fall. That will give you a good reboot as well. If this continues I would definitely contact support. I will look back through my files but I cannot remember an issue like this with my Vertical using either production firmware or newer FT firmware.

For the record.
Reboot did the trick. The recorded track is spot-on again.

New firmware and after a factory reset for my battery drainage problem. Second run after all that and first at this location so basically the same symptoms as before w offset tracks

I sent my logs to Suunto today. Not sure if I have a problem but with my experience I certainly would not describe the GPS accuracy as groundbreaking or phenomenal
