摘　　要：随着经济的不断发展,移动GIS越来越受到人们的关注,而GEOXT的出现正是符合这一发展趋势的产物。GEOXT这一款仪器将GPS与GIS结合在一起,利用GPS技术得出GIS的成果。文中在说明天宝GEOXT数据采集系统配置及特点的基础上,通过实验总结了数据采集的3种模式:单机码相位测距、后差分改正和实时差分改正数据采集,并对数据采集的技术流程、点位精度、特点和应用范围进行了阐述。最后对不同采集时间间隔对精度的影响进行了试验研究。Along with economic development, mobile GIS attracting increasing attention, of the emergence the GEOXT accorded with this trend. The GEOXT apparatus combines GPS with GIS, using GPS technology educes GIS results. Based on a brief statement to the GEOXT data acquisition system configuration and features, three modes of data acquisition were summarized by experiment： single phase code measure distance, post-operation difference correction, and real-time difference correction for data acquisition, and technology process, the position accuracy, characteristics and application scope of every data acquisition were elabortated in this paper. Finally, influence of accuracy for the acquisition of different time intervals was researched by the tests.
