his study aims to develop practical system for "periodical health check of slope stability" based on the achievements by Fukuoka on the high-precision-monitoring of ground movement by Short-time Real-time Kinematic (RTK-) GPS survey funded by the Grant-in-Aid for Scientific Research (Fundamental Research C) from 1999 - 2000. In this study we have tried to obtain observation data, to develop techniques, instruments, and software necessary for development of the system.(1)Procedure to transfer in realtime survey data from RTK-GPS receivers to PC was decided the, and specification of the displaying and editing programs to compare them with previous survey data was examined. A new RTK-GPS data display system was developed consisting of a handy PC with a wireless handy display which is light enough to hold on a hand. This system can display obtained data and evaluate them in realtime on site in 640 x 480 dot display. This system shows the position of RTK-GPS receiver antenna on the horizont … More al plane at every 1-second as well as histogram of obtained location data along east-west, north-south, and up-down axes. This system helps for to evaluate the precision, accuracy, and quality of the RTK-GPS survey data in realtime and on-site, to edit the data, and to extract ground movement vector on site by comparing with previous survey data. This software is now provided to RTK-GPS users through the co-investigators.(2)the Head Investigator gave the right of the automatic servo-control tripod for RTK-GPS survey, which was developed in the Grant-in-Aid for Scientific Research - Fundamental Research (C)(2), to Kansai TLO. Kansai TLO has applied this automatic tripod for a patent in December 2000 and gave the right to execute exclusively this patent(-to-be) to MARUTO Co., Ltd., Tokyo. This company has developed sell model and it will be on sale in 2004.(3)Landslide movement monitoring was repeated in Nuta Landslide in Kochi Prefecture, Zentoku Landslide in Tokushima Pref., and Okimi Landslide, Niigata Pref. Obtained data were compared with other previous observation data of extensometers, borehole inclinometer, total station survey, and static GPS monitoring data, and it shows good correlation. Especially in Okimi Landslide site, differential landslide movement was observed. Less

他的研究旨在基于福冈市在科学研究补助金（基础研究C）资助下通过短时实时动态（RTK-）GPS测量高精度监测地面移动的成果，开发实用的“斜坡稳定性定期健康检查”系统1999 - 2000年。在这项研究中，我们试图获得观测数据，开发系统开发所需的技术，仪器和软件。（1）确定了实时测量数据从RTK-GPS接收机传输到PC机的程序，并对显示和编辑程序的规格进行了审查，以便与以前的测量数据进行比较。研制了一种新型的RTK-GPS数据显示系统，该系统由便携式PC机和无线便携式显示器组成。该系统可在现场以640 × 480点阵显示器实时显示采集数据并进行评价。该系统显示了RTK-GPS接收机天线在水平面上的位置， ...更多信息 以及沿沿着东西、南北和上下轴获得的位置数据的直方图。该系统可对RTK-GPS测量数据的精度、准确度和质量进行实时、现场评价，并可对测量数据进行编辑，通过与以往测量数据的比较，可在现场提取地面移动矢量。该软件现在通过共同调查员提供给实时定位系统用户。（2）首席研究员将在科学研究补助金-基础研究（C）（2）中开发的用于RTK-GPS测量的自动伺服控制三脚架的权利授予关西TLO。关西TLO已于2000年12月申请了该自动三脚架的专利，并将该专利的独家执行权授予了MARUTO Co.，有限公司、东京该公司已开发出销售模式，并将于2004年开始销售。（3）在高知县的怒田滑坡、德岛县的善德滑坡中，与以往的伸缩仪、钻孔测斜仪、全站仪测量、静态GPS监测等观测资料进行了对比，显示出良好的相关性。特别是在冲见滑坡现场，观察到差异滑坡运动。少
