【摘要】：為提高天文定位系統(tǒng)的定位精度,減小傾角傳感器安裝誤差對系統(tǒng)水平測量精度的影響,對系統(tǒng)中傾角傳感器的安裝參數(shù)標定及校正進行了研究.首先,給出基于傾角傳感器的天文定位系統(tǒng)工作原理,分析傾角傳感器安裝過程中存在的誤差源.然后,提出一種通過對天文定位系統(tǒng)進行改造,利用系統(tǒng)自身完成傾角傳感器安裝參數(shù)標定的方法,并給出了傾角測量數(shù)據的校正算法.最后,建立三視場天文定位系統(tǒng)仿真測試平臺,對標定方法的性能進行了分析和驗證.實驗結果表明:該傾角傳感器安裝參數(shù)標定方法的標定精度與傾角傳感器自身測量精度保持一致,在全量程范圍內校正后的傾角測量結果最大誤差為4.315 5″,基本滿足天文定位系統(tǒng)中高精度傾角測量要求.
[Abstract]:In order to improve the positioning accuracy of the astronomical positioning system and reduce the influence of the installation error of the inclination sensor on the horizontal measurement accuracy of the system, the calibration and correction of the installation parameters of the inclination sensor in the system are studied. The working principle of astronomical positioning system based on inclination sensor is given, and the error source in installation process of inclination sensor is analyzed. Then, a retrofit of astronomical positioning system is put forward. The calibration method of the installation parameters of the inclination sensor is completed by the system itself, and the correction algorithm of the inclination angle measurement data is given. Finally, the simulation test platform of the three-field astronomical positioning system is established. The performance of the calibration method is analyzed and verified. The experimental results show that the calibration accuracy of the calibration method is consistent with that of the inclination sensor itself. The maximum error of the corrected obliquity measurement in the range of full range is 4.315 5 ", which basically meets the requirement of high precision inclination measurement in the astronomical positioning system.
