Abstract:A preliminary study was carried out to analyze the pseudorange multipath effect from reference stations of Continuous Operation Reference System (CORS) in Hebei province from the following four aspects. 1)A comparison was made among the pseudoramge multioath effects under different cutoff elevation angles(5°, 15° and 25°) and then the relations between the multipath effects and elevation angles are figured out. 2)All the reference stations are equipped with the same type of combinations of receiver and antenna, the discrepancy of the multipath can mainly due to the distinct environment of each receivers, taking several typical multipathaffected severely stations as examples, based on the basis of the skyplot of multipath, the effects of azimuth and elevationdependent effect of multipath were exactly examined, at meantime, a filed inspection of environment surrounding the stations was held, and the abovementioned factors further was verified.3)The dataset respectively from the strongest and weakest multipathaffected reference stations at the same day was processed, and the influences of multipath on the convergence time and repeatability of PPP solutions further were examined.
