摘要
推导了POS系统视准轴误差检校的数学模型,提出将POS系统的同步差作为一项检校内容,并给出了严格的同步差估算方法。试验表明,顾及同步差的视准轴误差检校精度与转换所得的角元素精度均有明显提高。
The function model of boresight misalignments calibration is derived, and the synchronization error of POS system is considered as an item of calibration, and a strict estimation method for the error is put forward. The experimental results show that the accuracies of calibrated boresight misalignments and angular elements conversation are remarkably improved while considering the synchronization error.
