GNSS Positioning for National Spatial Reference System Modernization: Tools, Products, and Applications

Session ID#: 282330

Session Description:
This session focuses on technical and operational advances supporting development, implementation, and use of the modernized National Spatial Reference System (NSRS). We invite contributions on GNSS-based positioning methods, reference frame realization, and datum modernization workflows that enable accurate, scalable adoption of new NSRS reference frames and supporting products across geospatial applications.

   Topics include multi-frequency/multi-constellation GNSS processing, precise point positioning (PPP), PPP-RTK, real-time network (RTN) integration and alignment, OPUS-based solutions, and consistency between real-time and post-processed positioning products. Contributions addressing atmospheric and satellite error mitigation, ambiguity resolution, quality control, and automated CORS monitoring are encouraged.

   We particularly welcome studies on time-dependent and kinematic reference frame implementation in regions of crustal motion, interoperability with legacy datums, and reproducible transition strategies for operational users. Application-focused submissions are encouraged where they assess GNSS accuracy, robustness, or datum transition performance in surveying, mapping, georeferencing, and operational geospatial workflows.
