摘要
分析了传统航天测量船无线电测量设备方位零位标校方法的优缺点,提出了一种不需大地测量的新标校方法,推导了计算公式,并对标校精度进行了系统分析。标校结果显示,该方法与传统方法相比,标校误差在3″以内,完全满足标校精度要求,且周期短、协调量小,可节省大量的经费。本标校方法可以进一步扩展到其它项目的标定。
The advantages and disadvantages of the traditional azimuthal zero values calibration method for TT＆C ship＇ s radio measuring equipment are provided. A new calibration method without geodetic survey is proposed, the calculating formula is concluded, and its precision is analysed. The calibration result shows that compared with traditional method its error is less than 3″, which meets the precision requirement of shipborne radio equipment calibration. It also reduces the calibration period and coordination quantity, as well as a plenty of cost. This method can be extended to other calibration projects.
