【摘要】 恶劣的工作环境给进一步提高捷联系统的性能带来了较大的困难，究其所有误差源，系统中的动力调谐陀螺误差对系统的精度影响较大。为此，本文主要对“捷联式定位定向系统”中动力调谐陀螺的误差作分析与研究。本文结合“捷联式定位定向系统”的特点，对动力调谐陀螺的主要漂移误差进行了分析，接着根据推得的动力调谐陀螺的静态、动态误差模型，提出了相应的误差补偿算法，并设计了误差实时补偿软件。最后经仿真计算，证明其补偿效果较好。更多还原

【Abstract】 Due to the worse working environment of SPADS, it is difficult to increase the performence of SPADS. As a result of analysing all error sources, dynamically tuned gyro error has a greater influence upon the accuracy of system. This paper analyses the main drift errors of the dynamically tuned gyro for SPADS in detail. The error compensation algorithem is proposed and the real time error compensation software is designed based on the model of the static errors and dynamic errors. The results of simulation indicates that the compensations are effective.更多还原
