Abstract
This article reports a positioning with GPS from Tsukuba to Kamioka over a distance of 250km. In the present work, we proposed a GPS positioning for a very long baseline positioning among a several of existing techniques. In fact, the precision of the positioning has been demonstrated in the neutrino experiment (particle-physics experiment) carried out between Tsukuba and Kamioka. The very long-baseline GPS positioning is one of techniques expected to be utilized in civil engineering when GPS continuous observation stations are completed by GSI (Geographical Survey Institute). The present work gives useful technical suggestions and prospects for future applications of long baseline GPS positioning in civil engineering.
