摘要：Carrier phase measurements are always used in high precision situations. Though in short baseline case, double difference technic can eliminate most of the systematic errors, some errors still remain. Therefore, the stochastic characters and measurement quality of carrier phase is of vital importance. In this paper, the residuals of zero baseline and short baseline carrier phase are evaluated. Then the observation qualities of carrier phase from different frequencies are analyzed. Besides, the multipath of pseudorange is also investigated. The result showed that in zero baseline case the accuracy of B3 carrier phase is always worse than that of the B1. But, in general, the accuracy of all satellites at the B1 and B3 frequencies is high which ranges from 0.15mm and 0.35mm. In short baseline case, the accuracy of carrier phase is related to satellite elevations. The carrier phase accuracy is worse than that of the zero baseline case which is about 2mm but is better than 1/100 wavelength. The multipath of the three frequencies has a relationship which is B1 > B2 > B3. This is related to different wavelength and code length.
