Abstract
By multi-GNSS techniques, use of high accuracy satellite positioning is increasing. When we use satellite positioning, in most cases, obstacles are existing around rover station. For example, trees and structures might be obstacles for satellite positioning. The obstacle can reflect the wave from satellite and that occurs problems to satellite positioning. It causes bad accuracy of satellite positioning, and sometimes it is impossible to get positioning solution. These problems are often solved by changing positioning settings.
In this paper, authors summarized about settings that can improve positioning performance, and consider the effect of changing settings. In addition, authors mentioned about improvement of positioning performance by multi-analyze on different settings.
