Device jumps

I have problem with GT06, LT05 devices.

From one moment to another, in seconds it jumps to location and then returns to the initial location. What could be the problem.




In the example above, in 1 second he made a big jump of location, and this affects the total distance because these jumps accumulate.

And so the tour remains at the end of the day.

Have you checked raw data? Maybe there's some issue with time?

I will review the hexes and share them later here

This is log

Hello, did you solve this problem?? I am also having it with my equipment that uses the GT06 protocol.

I have same problem with a new bunch of TK103 clones. Seems that device records and retain coordinates when it don’t have solid GSM signal. When it acquires good signal, start sending history mixed with actual device location, causing that jumps. Until now I don’t have a fix for that.
