一、目的意义物探测量作为地震勘探施工的先行军,其施工的效率和资料的准确性直接影响和制约着整个地震队伍的施工进度及后续资料解释的完美性。目前物探测量的施工方法为常规测量和常规RTK测量模式,其间存在许多影响施工效率和资料准确度的因素,如传统RTK技术存在着定位距离短(15 km)、电台传播差分信号数据受限、初始化时间长、参考站位置选取及架设费时费力、流动站受制于距离及地形限制等缺
I. Purpose Geophysical survey As the forerunner of seismic exploration and construction, the construction efficiency and data accuracy directly affect and restrict the construction progress of the entire seismic team and the perfection of subsequent data interpretation. At present, the construction methods of geophysical surveying are conventional surveying and conventional RTK surveying. There are many factors that affect the construction efficiency and data accuracy. For example, the traditional RTK technology has short positioning distance (15 km), limited data of radio differential signals, Initialization time is long, the reference station location selection and erection time-consuming and laborious, mobile station subject to distance and topographic restrictions and other lack
