| Abstract: | A field absolute calibration procedure developed by Geo＋ q is introduced in this paper. Multipath influence can be eliminated and the PVC depended on azimuth can be obtained by this method. After further research, this procedure can provide efficient and ac curate variations in realtime. Give an example of the absolute PCVs for one type of antenna. and finally the accuracy requirements for PCV corrections are introduced. |
