How do I get antenna phase center information for CORS antennas?
Use this link NGS GPS Antenna Calibrations and then scroll down on the page. Select the “Complete” Relative Antenna Calibration Results link under Antenna Calibration Resources. Right-click on the “Complete Relative Antenna Calibration File” link and save it to your hard disk. Open up SKI-Pro and go to the Antenna Management page. Right-click in either the Contents area or the Antenna list area and select “Import Antenna File…”. Locate, select and import the file. It is typically named Ant_info.003.txt.
