摘　　要：为了提高飞机在持续高动态场景下的姿态测量精度,并保证自主性,提出了一种基于微惯性导航系统(MINS)和大气数据系统(ADS)组合的捷联姿态算法。在航向信息缺失的前提下,推导了简化姿态更新算法和载体系速度更新算法,减小了计算量;通过引入大气数据系统的真空速信息,设计不依赖航向信息的MINS/ADS速度组合算法来提高姿态精度。飞行实验结果表明,与传统地平仪算法相比,所提算法的俯仰角和横滚角精度分别提升了74.32%和69.62%,环境适应性更强。In order to improve the attitude measurement accuracy of the aircraft in the continuous high dynamic scene and ensure the autonomy,a strapdown attitude algorithm based on the integration of micro inertial navigation system(MINS)and air data system(ADS)is proposed.Under the premise of heading information missing,a simplified attitude update algorithm and a carrier system speed update algorithm are derived to reduce the amount of calculation.By introducing the true air speed information of ADS,a MINS/ADS velocity integration algorithm independent of heading information is designed to improve the attitude accuracy.The results of flight experiments show that compared with the traditional horizon algorithm,the accuracy of pitch angle and roll angle of the proposed algorithm is improved by 74.32%and 69.62%respectively,and the environmental adaptability is stronger.
