基于星座图的QPSK仿真，易于理解QPSK的原理(QPSK constellation based on simulation, and easy to understand the principles of QPSK)

惯性导航，利用惯性元件（加速度计）来测量运载体本身的加速度，经过积分和运算得到速度和位置，从而达到对运载体导航定位的目的。组成惯性导航系统的设备都安装在运载体内，工作时不依赖外界信息，也不向外界辐射能量，不易受到干扰，是一种自主式导航系统。(Inertial navigation, to measure the carrier itself acceleration Inertial element (accelerometer), through integration and operation to get the speed and position, so as to achieve the purpose of vehicle navigation. Inertial navigation systems equipment components are installed in the carriage of the body, does not rely on external information work, not to the outside world-radiation energy, less susceptible to interference, it is an autonomous navigation system.)
