摘要
通过介绍七参数的原理及其求解方法,运用GPS静态测量建立控制网求解七参数,然后使用七参数法和两点校正法GPS-RTK测量已知点,通过分析两种方法获得的实验数据,得出两种方法的优缺点,确定了在什么情况下使用七参数法GPS-RTK测量最优,什么情况下使用两点校正法GPS-RTK测量最好。从而既能保证测量精度,又能提高工作效率。
By introducing the principle and solving method of the seven parameter,this paper uses the GPS static measurement to establish the control network to solve the seven parameters,then uses the seven parameter method and the two point correction method RTK to measure the known points,and through the analysis of the experimental data obtained by the two methods,the advantages and disadvantages of the two methods are obtained. Under what circumstances,the seven parameter method RTK measurement is used. The amount is optimal. Under what circumstances,we use the spot correction method RTK to measure the final. It can not only guarantee the accuracy of measurement,but also improve the work efficiency.
