无线电辅助捷联惯性导航系统的设计及工程实现

为确保飞行器在没有GPS（全球定位系统）信号的情况下仍能保持高精度导航能力，在SINS（捷联惯性导航系统）/GPS/Altimeter（高度表）组合系统的基础上，设计了Radio（无线电）辅助SINS组合导航系统。该系统通过一定的组合算法将SINS与无线电信息有效组合，不仅可以满足系统精度的要求，而且工作可靠、输出信息平滑稳定。本文介绍了该系统的原理、设计方案、组成以及工程技术难点。飞行试验结果显示该系统能够满足设计精度要求，为系统在恶劣条件下的应用提供了一个有效的解决方案。

The Design and Engineering Implementation of Integrated Navigation of SINS/Radio

Based on SINS/GPS/Altimeter navigation system, an airborne SINS/Radio/Altimeter assistant navigation system is designed to ensure the high precision navigation in case of GPS signals jamming. By certain Algorithms, the SINS and Radio signal was integrated effectively. The system can obtain the high position accuracy, high reliability. The outputs of the system is smooth and steady. This paper will focus on the study of the system principle, the mechanization and engineering implement. The result shows that the designed system can meet accuracy requirement of the navigation system under the badly circumstance.
