捷联惯导系统的导航算法，采用卡尔曼滤波对惯性信息和GPS信号进行融合，进行噪声处理-SINS navigation algorithm, Kalman filtering fusion of inertial information and GPS signal, noise processing

通过matlab进行卡尔曼滤波，对温度和噪声后的信息进行估计-Calman filter is carried out by MATLAB, the temperature and after the noise estimate information

二阶格型滤波器可以较好的对信号进行噪声滤波，提高信噪比，误差较小，收敛速度较RSL快(The two order lattice filter can filter the signal better, improve the SNR, the error is small, and the convergence speed is faster than that of RSL)
