惯导RTK技术的定位原理和工程应用实践CSCD

传统的实时动态定位(RTK)技术测量时必须使全球卫星导航系统(GNSS)接收机天线相位中心与测量点保持相对垂直才能够保证测量成果精度,测量时一般要架设三脚架;当使用对中杆测量时,测量者必须保证对中杆水准气泡相对居中才能保证测量成果的精度,测量过程较为费时费力.惯性导航系统(INS)的出现,改变了人们对传统RTK测绘技术的应用习惯,测量过程中一般不需要架设三脚架,测量对中杆在一定范围内保持任意的倾斜状态,测量过程相对轻松自如,大大减轻了测量工作劳动强度,提高了测绘工作效率.论文主要分析了INS的定位原理和其技术优势,并强调了只有熟练掌握惯导RTK技术在实际应用中的注意事项,才能使其发挥最大的效益与效率.

Positioning principle and engineering application practice of Inertial Navigation System RTK technology

When using the traditional real-time dynamic positioning (RTK) technology, one must keep the antenna phase center of the Global Navigation Satellite System (GNSS) receiver relatively perpendicular to the measurement point during the measurement to ensure the accuracy of the measurement results. Generally a tripod should be erected. When using the centering rod for measurement, the surveyor must ensure that the leveling bubble of the centering rod call is relatively centered in order to ensure the accuracy of the measurement results. The measurement process is time-consuming and laborious. The emergence of Inertial Navigation System (INS) technology has changed the traditional habit of RTK Surveying and mapping technology. In the measurement process, there is generally no need to erect a tripod, and the measuring centering rod maintain an arbitrary tilt state within a certain range. The measurement process is relatively easy and free, which greatly reduces the labor intensity of measurement and improves the efficiency of surveying and mapping. This paper mainly analyzes the positioning principle and technical advantages of INS technology, and emphasizes that only by mastering the precautions of INS RTK technology in practical application, can it give full play to its maximum benefit and efficiency.
