绘制高斯曲面，能够帮你学习高斯曲面的绘制，给您节省时间。(Gaussian surface drawn to help you learn the Gaussian surface drawn to save you time.)

通过遗传算法对神经网络的结构进行优化,避免参数选取的盲目性(Through genetic algorithms to optimize the structure of neural networks, to avoid the blindness of parameter selection)

说明：  直接序列扩频代码，完成直接序列扩频的扩展功能(Direct sequence spread spectrum code to complete the extended functionality of direct sequence spread spectrum)

利用GNSS 进行高精度导航定位的前提是正确固定载波相位观测值的整周模糊度。由Galileo 系统的4 个载波观测值可以 形成诸多有良好特性的组合观测值,利用这些组合观测值,结合MCAR 方法,可以有效地确定整周模糊度。(The use of high-precision GNSS navigation and positioning the premise is correct carrier phase observations fixed integer ambiguity. May consist of four carriers observations Galileo system There are many good characteristics to form a combination of observations using a combination of these observations, combined with MCAR method can effectively determine the integer ambiguity.)
