Abstract:	The phase interference system precision measurement using GPS has been developed in the field of civil engineering survey, but not so much as expected. The precision measurement using GPS is effective in the crustal movement observation such as volcano monitoring and the landslide observation, and has been widely used for such applications. However, we have difficulties in observation using equipment for civil engineering survey in the field; on the other hand, only the system incorporating the sensors power supply and communication means is required to make it into practice. Usually, we have to face with the fact that it is very difficult to install the system in the location where there is a volcano or landslide under stringent environments because power supply and communication cannot be obtained easily. We succeeded in putting the system to use which can continuously observe the displacement with high accuracy realized by statistically processing the data in real time in stringent environments. In Japan, our group has already installed more than 100 systems operating in the stringent environment from the viewpoints of communication and power supply. The practical use of the system is largely contributed not only by our GPS, communication, and power supply technologies but also by our experience cultivated in such environmentally stringent fields. For prevention of disasters due to volcanic eruptions and landslides, it is necessary to realize both two-dimensional and three-dimensional data measurements so far not performed to grasp the mechanism. The conventional sensors do not work well for this purpose and only the GPS technologies could help. The actual cases where the system was realized are introduced together with the associate technologies.
