摘要: Multipath remains a major error source in both static and kinematic positioning. For example, it takes toll the carrier phase, causing receiver to measure distorted phase. Various improvements antenna technologies, as well modelling strategies, have resulted better ways of coping with this source. has been shown be highly correlated for an array closely spaced antennas. This fact allowed various investigations using different antenna/receiver configurations. In our investigation, we used configuration based on two antennas linked single GPS receiver. Our methodology introduces temporal factor measurements, assumption that multipath parameters satellite geometry slow variation time space. paper presents spectral analysis, which intends evaluate performance estimation process. The analysis compares estimated signal original input data feeds
