AbstractThe technique of accounting satellite and receiver antenna phase center offset in Global navigation satellite systems is shown in the article. Also experimental results that show the significance of accounting such offsets in Precise Point Positioning are outlined. Technical reasons of appearance antenna phase center offsets are considered in the article. Experimental results are provided for post-processing high precision user coordinates estimation process in absolute mode.
