Automated Methods for Correcting ODOT's Real-Time GNSS Network for Survey and Post-Disaster Recovery

The main objective of this research is to develop a near real-time methodology for automatically flagging and correcting ORGN reference stations that are misaligned with the satellite based National Spatial Reference System (NSRS). The objective of this study will be achieved by: (1) Investigating alternative techniques and methodologies used for monitoring permanent static GNSS networks such as precise point positioning (PPP); (2) Developing, in collaboration with NOAA’s National Geodetic Survey (NGS), the necessary algorithms and workflow, which will include recommended best practices for housing and disseminating raw GNSS data, for the purpose of automatically adjusting and aligning the ORGN to the NSRS; (3) Identifying optimal statistical variables and tolerances to quantify the health of ORGN base stations; and (4) Producing a web-based graphical user interface(s) sharing updated ORGN coordinates and time-series plots for ORGN operators and surveying practitioners.
