Map image does not match GPS

Guigo2 years ago

Good morning, I'm using traccar V. 5.9, My system is not accurate on the maps, whether using SmartPhones, or using the Sino track 906 L Tracker, looking at the image you can have a base that when passing through the Bridge the path was as follows. What can this be ?

Could be a map error or maybe reflected GPS signal.

And logicly you checked the real coordinates that the tracker sends to traccar server from the server log. And compared those coordinates in Google maps to see if there is any difference?

Hi,
I have the same problem with at least one tracker, I will check tomorrow if the problem comes from the tracker itself, but in this case is there an option to apply an offset to the received positions of one device?
