一种新型的地震测量仪器──MANPACK DGPS系统
|
摘要
MANPACKDGPS系统是法国SERCEL公司于1993年4月投放市场的一种新产品。这套系统是专为进行二维、三维和弯曲测线快速地震测量设计的。它的实时测量精度小于1m，经后处理后的精度可达40～50cm。此系统由三部分组成：①一个用以发射差分校正值的小型灵活的差分参考站NDS200；②一个装有罗经和实时质量控制的智能型便携式实时差分和GPS集成接收机，并带有GPS／HF二合一天线和活动式存储卡；③一台用于地震测线设计、后处理及质量控制的个人PC486微机。此系统的三维测量精度和效率均已在野外生产中得到了验证。
MANPACK DGPS System is a new product which was put into market in April.1993 by French Sercel corporation. It was specially designed for quick 2D, 3D and slatom line seismic surveys. Its real time accuracy is better than 1m, and the postprocessing accuracy is 40～50cm. The system consists of ① a portable NDS200 reference station for transmitting differential correction signals ；② portable intellect differential & GPS integrated receiver,which has a single GPS/HF antenna,movable memory card,built-in compass and QC function in real time;and ③ a PC486 computer for seismic layout design,postprocessing and quality control, Both the accuracy and the productivity of 3D. seismic survey using this system have been proved in field work.
