NGS Updates for June 2025

Last week NGS released the Multiyear CORS Solution 3 (MYCS3) updates. This had many impacts including:
- Updated positions and velocities for all CORS in the NOAA CORS Network (NCN).
- New coordinate functions for NCN stations consistent with ITRF2020.
- OPUS will not provide solutions based in ITRF2020.
- RTN operators will likely be updating station coordinates.
This week multiple NSRS Modernization products were released into Beta. Moving these products from Alpha to Beta is a big deal since these products are expected to be close to what will be released once going to Production.
New Terrestrial Reference Frames of 2022
Euler Pole Parameters of 2022 (EPP2022) - models for tectonic plate motion.
North American-Pacific Geopotential Datum of 2022 (NAPGD2022) includes:
Models for GEOID2022, DEFLEC2022, GRAV2022.
Beta NAPGD2022 Experience to evaluate models and differences from current datums/models to new datums/models.
State Plane Coordinate System of 2022 (SPCS2022)
Going from 125 zones to 972 zones. All zone definitions finalized.
Beta SPCS2022 Experience to evaluate the distortion for all zones.

Beta NCAT - updated version of NCAT that incorporates all the SPCS2022 zones. (There are still significant updates coming for NCAT since it will need to incorporate transformations to new datums once those are done)
