惯导系统中通常基于小角度条件作为线性条件。对比正余弦函数小角度近似前后的误差。自己编写的m程序-Codes show how the tiny-angle-approximation cause errors.

As the computer hardware developing and the fast advances of computers in the last several years, Monte Carlo particle filter algorithms, which origin Monte Carlo methods, have become popular again. The Monte Carlo particle filter algorithms in thi
