It is probably the normal fluctuation that the gps has when it is stationary.
I think you just need to turn on static navigation on your locator
thank you for your answer, what do you mean by static? It seems that the problem comes from the platform, the JAVA, right? What do you think ?
I agree with Nicola but if you want some custom handling for this, there is some filters you can apply also in the traccar.xml file. Check the traccar documentation on this page
Do you use Teltonika?
If so, find the documentation here, which will be similar for other brands

Otherwise you can do it directly from Traccar as Lucas says
