get the E corridinate pretty close but struggle with N and U.


In regards to XYZ in my setup on Reach M2, they use Ellipsoidal (EL) Height, which is not the
same as the Orthometric (ORTHO) Height: The Difference Between Ellipsoidal, Geoid, and Orthometric Elevations?

In regards to XY, I can see them change in real time, and with WAAS, upto some 16" total length (8" on each side) range and less.

Tidbit Affecting GPS - Ionospheric activity: We are approaching the peak years of the latest solar cycle (the 25th since the phenomenon was tracked), which will peak in 2025.
During this period, space weather events like solar flares and coronal mass ejections (CME) will occur. During such events that can last one or more days, you may experience long fix times, inability to fix, or high residuals.

=====================================This topic End

Tidbit - The standardized GPS and GLONASS RTCM-3 messages, which cannot be effectively extended to other GNSS systems and other signals, are limited to L1 and L2 frequency bands and to only one signal per band. MSM (Multiple Signal Messages) added in RTCM-3.2 realizes the maximum compatibility with RINEX-3 and is used to replace legacy RTCM-3 messages (such as MT1001-1004, MT1009-1012).
