STEP 6: Selecting CORSs

Choose the most suitable CORS to serve as controls for session baseline processing and network adjustments. To add CORS and IGS Stations to the project, click on the “Add/Del CORS” button on the Managers Page, which will open a pop-up window, as shown in Fig. 7. It is recommended to select between 4 to 8 stations, which should include at least one station located within 200 km of the observed user marks to function as a session baseline processing “hub station”. To model tropospheric delay, it is advisable to add a remote station at a distance of 375 to 800 km. Please refer to Section 8 for a comprehensive, step by step guide.
