NGS Announces Plans for the Modernized NSRS

Friday August 7, 2020

NGS has issued two Federal Register Notices (FRNs) concerning the National Spatial Reference System (NSRS), the nation’s geodetic coordinate system. The first notice announces upcoming changes to the NSRS, which is being modernized. Initial rollout of the modernized system is expected between 2022 and 2025. As part of the modernization process, NGS is considering imposing a time limit on the coordinate observations that comprise the NSRS, but would like to conduct well-structured, data-driven experiments before imposing this limit. Therefore, NGS has issued a second FRN that requests users take new Global Navigation Satellite System observations on geodetic control marks of interest, especially those marks that have not been surveyed since January 1, 2010, and share them with NGS before December 31, 2021.
