摘要
微动勘探方法对微动台阵中各测点位置的精度要求较高。利用GPS定位技术设计了微动台阵的精密定位系统,介绍了系统的设计原理及软硬件组成。实验结果表明,该系统的定位精度可以达到厘米级,并能较方便地进行微动台阵的布设作业。
Accurate relative position of each site in array is required for microtremor exploration.A precise positioning system has been designed by use of GPS,its principle and constituent parts of software and hardware are introduced and test results are given.It is shown that the accuracy of the system is on centimeter level and it is convenient for microtremor array disposition.
