Try post-processing,,,need help!

Hi, This evening I try to log data for post processing. I set base and rover in single default config.
then just now i processed them. Actually I don’t know what happen.The result is not good enough I think. This is the pictures and the log data, maybe someone can help me to improve this.
And the real fact is, my cors base station is error, so my reach base station coordinate is set in single possition method first. And I don’t have any other support data such as sbas, qzzs, or cors base station.

This is 25 deg elev mask

This is 30 deg elev mask

My base data log is here
And my rover is here
Base coordinate is here

I set my rtkpost according to reach rtk-post docs
