STEP 4: Load Static GNSS Observation Files

Load static GNSS observation files through the OPUS upload portal, as shown in Fig. 5. If your project contains GVX files and you plan to submit your project to NGS, ensure that you upload Non-NCN CORS data files, such as static GNSS observation files from RTK/RTN Base or Reference Stations, from the days of your RTK/RTN survey following the static observation requirements.
