Abstract
Based on the geomagnetic declination survey's theory and technology,the deviation model is built from the effect of the different GPS reference points' position selection on the geomagnetic Declination survey accurate evaluation.Then,the deviation analysis is carried on and the relative curve diagram is plotted between the geomagnetic deviation and the GPS base line distance.According to the data analyzing result of the error model estimation example,the regularity of the relative error changing and the methods of GPS points' position selection are obtained with which the GPS baseline points' error can be fallen into the predictive error areas and the accuracy of geomagnetic declination survey can be met with the specification.关键词
