| Abstract | 高精度测量射电望远镜参考点和轴线偏差等参数,对建立天线指向模型和本地连接参数、提高测站坐标精度等具有重要意义。为完成新建射电望远镜参考点初始参考值的快速测定,根据望远镜的旋转模型,结合常规静态归心测量方法和随机动态测量方法,提出了一种利用GNSS天线代替测量靶标实现望远镜参考点测量的方法。通过仿真分析验证了该方法的合理性和有效性,并分析了数据点个数和数据点测量精度对天线参考点和轴线偏差解算精度的影响。 |
| Other Abstract | The measurement of the reference point and axis offset of the radio telescope with high precision is of importance to the establishment of the antenna pointing model, the local tie parameters and the improvement of the coordinates accuracy of the station. In order to complete the rapid determination of the initial value of the reference point of the newly built radio telescope, according to the rotating model of the telescope, combined with the common local survey method and the parameterized modeling of the antenna rotation survey method, a method to measure of the reference point of the telescope by using GNSS antenna instead of the measurement targets was proposed. The validity and rationality of the method are verified by the result of data simulation analysis. The effect of the number of data points and the precision of data points on the determination precision of antenna reference point and axis offset are also analyzed. |
