Constant 1cm precision with Here+V2 possible?

The title is self explanatory, is there any u-center or mission planner parameter configuration that allows this hardware to attain the 1cm precision?Because either using a base and leaving surveying for many hours or using ntrip with rover, I can’t get that precision.

Did you operate the GPS under open area? Environmental interference can cause dropping in accuracy.

Maybe you can try to survey longer?
