摘要
对目前飞行器的定位方案种类、两种陆基定位方案在使用方面的优劣进行了概述;对两种陆基定位方案在定位精度方面的优选问题进行了深入研究,提出了延时零位标定修正和定位解算及定位精度模型,在理论上证明了定位精度高的方案,用飞行试验实例仿真验算了理论证明的正确性;对定位精度高方案的延时零位的校正问题进行了总体计算论证,从总体上得出了不必进行零位漂移后重新校正的结论,综合得出了优选定位方案的结论。
The current aerocraft positioning scheme and the advantage and shortage of two kinds of land-based positioning, schemes in applications are introduced. The optimization choice problem of these two land-based positioning schemes in aspect of positioning accuracy has been lucubrated. The positioning calculation and positioning accuracy model are presented. The scheme with high positioning accuracy is abstractly proven and an example simulation of flight test is used for verifying the correctness of the proposed theoretical result. The correction problem of delay zero-position of the scheme with high positioning accuracy has been demonstrated and the conclusion of needless correction as a whole is educed. Finally, the conclusion of optimization choice of positioning scheme is given.
