This paper mainly talks about the combination of GIS and the newborn technology GNSS-R,elaborating the design and realization of the three dimensional data analysis system for airborne GNSS-R based on GIS,and presenting the software interface and data processing result of the three dimensional data analysis system.An application of the system is shown in the end of the paper,talking about the data processing and data analysis of the reflectivity at the specular point,and accessing the influencing factor on the specular point reflectivity.This paper provides a new method for GNSS-R data analysis.
