用最优化方法解决最优化问题的技术称为最优化技术，它包含两个方面的内容： (1)建立数学模型，即用数学语言来描述最优化问题。模型中的数学关系式反映了最优化问题所要达到的目标和各种约束条件； (2)数学求解，数学模型建好以后，选择合理的最优化方法进行求解。 (With optimization method to solve the optimization technology, called the optimum technology, it contains two aspects: (1) established the mathematical model, which is the mathematical language to describe the optimization problem. Model of the mathematical relationship reflects the optimal problem to achieve and all constraint conditions (2) solving mathematics, mathematical model built after, choice of reasonable solution of the optimization method.)

说明：  捷联惯导系统放置在室内测试台上做静态测试，测试时间4500s。 1）取前180数据做粗对准（解析对准法）； 2）取第181s~900s数据做精对准（Kalman滤波法）； 3）从第901s开始做纯惯导解算； 4）用国军标的导航系统位置精度评价方法评估系统定位精度（分别计算CEP50 和 CEP95 下的定位精度）。(The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s. 1) take the first 180 data for rough alignment (analytical alignment method); 2) accurate alignment of 181s-900s data (Kalman filtering method); 3) pure inertial navigation solution is performed from 901s; 4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).)
