| 摘 要： | 采用加速度计取代陀螺仪作为惯性测量元件构建的无陀螺惯导系统(GF-INS),具有成本低、体积小、机动性能好等优点,已成为近年来惯性技术应用领域的研究热点。文中从理论上分析研究了GF-INS加速度计的输出方程,提出了基于统一方程的GF-INS解算的一般过程,并进行了理论推导。研究表明,不同加速度计配置方案只是选取了不同的参数,解算本质是一致的。结合国内外相关研究成果,对GF-INS的研究与发展提出了若干建议。

| Abstract: | Gyro free inertial navigation system(GF-INS) substituting accelerometers for gyroscopes,because of many merits such as low cost,small size,and good maneuverability,has interested many researchers in recent years.The output equations of accelerometers in GF-INS were analyzed theoretically.The common computation process of GF-INS based on the unification equation was proposed and a theoretic derivation was done.The researching work shows that the calculation of dif-ferent configurations is coincident essentially despite some different parameters.Based on the domestic and overseas achievements,suggestions for the developments of GF-INS were brought forward. |
