单陀螺捷联航姿系统

Single Gyro Strapdown Attitude and Heading Reference Svstem

捷联航姿系统通常采用二个双轴速率陀螺仪和三个加速度计作为敏感元件。本文提出了一种新的捷联航姿系统方案,即单陀螺捷联航姿系统。该系统只采用一个双轴速率陀螺和三个加速度计作为敏感元件。文中给出了该方案的原理框图以及它的解算公式,同时给出了数字仿真结果。结果表明该方案精度完全能满足要求。

The sensors of a strapdown attitude and heading reference system,in general,are two 2-degree-of-freedom tuned ro- tor gyros and three accelerometers.This paper puts forward a new scheme-Single Gyro Strapdown Attitude and Heading Reference System.The sensors of this system adopt only one 2-degree-of-fre- edom tuned rotor gyro and three accelerometers.The block diagram of the principle and the formula of this scheme are given,the digi- tal simulation results have been presented in this paper.The results show that the accuracy of this system accords with the demands.
