CSRC published a new reference frame (geodetic datum) for California called “CSRN Epoch 2025.00 NAD83(2011)” on July 31, 2025 under a Caltrans contract to SOPAC/CSRC. The California Spatial Reference Network (CSRN) consisting of 1068 GNSS stations is the latest realization of the California Spatial Reference System. The new epoch-date coordinates are transmitted in CRTN's RTCM 3.3/3.4 data streams since August 11, 2025.
