L76 - Drift problem

Hi. I have a problem with the drift effect, after starting, in fix e.g. 14-16 satellites, it can make a error by 5-6 meters, only after some time in motion, it correctly indicates, is it normal?

Dear Sir

Normally, it takes time to converge after positioning to achieve higher accuracy.
The L76 accuracy described in the specification is CEP 2.5m, so this does not seem to be a problem.

Best Regards
