【摘要】 航道测量范围大、距离长并且跨省区,但CORS系统测量不能跨省区。针对这一问题,论述了RTK测量、CORS系统测量和千寻位置的定位导航技术。千寻知寸测量方法具有厘米级定位精度,覆盖范围全、无缝衔接、整体精度高,能满足大范围、长距离和跨省区航道测量要求,为类似工程测量提供了一种新方法。更多还原

【Abstract】 Channel survey covers a wide range,a long distance and spans provinces,but CORS system survey cannot span provinces. In view of this problem,this paper discusses RTK measurement,CORS system measurement and Qianxun CORS. The Qianxun Find CM measuring method has centimeter-level positioning accuracy,with full coverage,seamless connection and high overall accuracy,and can meet the requirements of large-scale,long-distance and span-provincial channel survey. It provides a new method for similar engineering survey.更多还原
