The National Geodetic Survey (NGS) is planning on a new reference framework, NATREF 2022 (but will likely be in 2025 or 2026). This is a significant shift, much like the change from NAD27 to NAD83, by as much as a foot in LA. The state has passed legislation to reflect this change. As we did with the shift from NAD83-CORS96 to NAD83-2011 (in 2012), our RTN will support both the new NATREF datum and the prior NAD83 datum as long as NGS does, and we will provide mountpoints for both, which will allow you to choose NATREF or NAD83 from the NTRIP Caster list of mountpoints.
