Here I want to show you how to update a ZED-X20P without u-center2.

I use the gpsd tool set since a while.

Tap on the image to see details.

After some tests with Precise Point Positioning ( see below 1-5 ) and in detailed with (4) I describe this time a setup with a base station sending RTCM (Radio Technical Commission for Maritime Services) data to a rover station.

Comprehensive Comparison: Precise Point Positioning (PPP) Methods This report documents the evolution of GNSS measurement techniques from basic statistical averaging to professional-grade post-processing and real-time RTK solutions.

This is now my fifth attempt and probably the last one to get a high precision position (using RTK) of my stationary GNSS antenna on the roof of my house.

This post will just describe how to setup a second interface on a Raspberry Pi4 and Pi5 with Debian 13 (trixie) for the second interface on the GNSS receiver called UART2.

Some days ago I got the new ZED-X20P from manufacturer u-blox.

This is now my fourth attempt to get an exact position (Precise Point Positioning) of my fixed mounted GNSS antenna at the roof of my house.

This is now my third attempt to get an exact position of my fixed mounted GNSS antenna at the roof of my house.
