摘要
Abstract
In the process of GPS receivers calibration, it is found that the measured antenna phase center of the same GPS receiver is different according to the calibration method of regulation JJF1118-2004, sometimes the difference reaches to the level of more than 3mm. There are many factors leading to this difference, including leveling error of base, influence of satellite signal quality, data acquisition time and solution error and so on. Calibration method affects this difference comparatively large through the analysis of the calibration method. The difference of GPS antenna phase center consistency is deduced in theory, and the results were verified by the experimental data. Experimental result demonstrates that the GPS antenna phase center consistency changes in certain range.关键词
