STEP 7: Select CORS

CORS Selection: select the best CORSs for use as control for session baseline processing and network adjustments. CORS and IGS Stations should be added to the project using the “Add/Del CORS” button on the Manager’s Page. Typically, 4 to 8 stations should be selected, including at least one within 200 km of the observed user marks to function as a session baseline processing “hub station.” A detailed, step-by-step procedure is provided in Section 9. Add one distant station (300 to 800 km away) to help model the tropospheric delays.
