说明：  用C++实现捷联惯导软件中的四元数计算随着面向对象技术的发展, 以及计算机内存容量 和硬件速度的不断提高, 在导航系统软件设计中采用 面向对象的思想正成为趋势, 使程序设计者的着眼点 真正从代码的编写、功能的实现转移到了对现实系统 的确切描述。面向对象的程序设计, 由于尊重现实世 界中对象的特征, 特别是对象的封闭性、继承性, 正 在软件设计的各个领域中成为主流。
(Using C++, software SINS quaternion calculated as the development of object-oriented technology, and computer memory capacity and speed of the hardware continues to improve, the navigation system software design using object-oriented thinking is becoming a trend The focus of the real programmers write code from the functional implementation of the system shifted to the exact description of reality. Object-oriented programming, because respect for the characteristics of objects in the real world, in particular, the closed objects, inheritance, being in all areas of software design into the mainstream.)
