| 摘 要： | 针对惯性导航系统成本较高无法广泛使用,设计了一种利用电子罗盘进行自主式初始对准的低成本微惯性导航硬件系统,并对信号进行预处理;经过罗差修正后的电子罗盘精度达到±1°以内,可以满足捷联式导航系统初始对准要求,借助"四元数"理论编写导航解算算法,确定载体的姿态、速度、位置;实验结果表明,该系统短期精度较高,可以应用在普通导航控制系统中,且大大降低系统的体积、重量、成本等,具有广阔的市场应用前景。

| Abstract: | As cost is too high,inertial navigation system can't satisfy the requirements of wide application, a low-cost micro-inertial navigation hardware system with electronic compass for the use of self-initial alignment is designed,and signal is preprocessed,after environment error compensation the precision of electronic compass achieves one degree,and can satisfy the requirements of initial alignment. With the theory of "quaternion" to complete stapdown algorithm and then to calculation the carrier's attitude, ... |
