二重差誤差の解析によるGNSS測位性能の改善

抄録

In this paper, we propose a satellite determination method based on the magnitude of the absolute value of the double-difference. Conventional satellite selection methods based on the visibility of a satellite have the problem that it is challenging to decide the boundary of visibility and that invisible satellites can also be used sufficiently in some cases. Therefore, this study focuses on the relationship between the DGNSS positioning error and the standard deviation of the double-difference, and then evaluates the effectiveness of the proposed method using the true value and the precision calendar as primary research. As a result of applying the proposed method, the standard deviation of the double-difference was reduced and the positioning error was improved at about half of the positioning points.
