How to improve the topic(/gps/fix) output precision, retaining 10 decimal places

[miku54]

Hello everyone, please tell me how to improve the topic output accuracy of zed-f9p (ublox_driver), such as the lla data of /gps/fix. When I run the demo, the altitude read always only has 3 digits after the decimal point. , longitude only has 7 digits of data after the decimal point. How to change to retain 10 decimal places? Do I need to configure anything in u-center? In addition, I have set UBX-CFG-NMEA to high-precision mode, but it has no effect. Desktop (please complete the following information):

• OS: [ Ubuntu 18.04]
• ROS Version [ ROS1 Melodic]
