绘制了24课GPS卫星围绕地球旋转的动态图(A dynamic map of the rotation of GPS satellites around the Earth in lesson 24 has been drawn.)

说明：  在AM信号中，载波分量并不携带信息，仍占据大部分功率，如果抑制载波分量的发送，就能够提高功率效率，这就抑制载波双边带调制DSB-SC（Double Side Band with Suppressed Carrier），简称双边带调制（DSB）。(In AM signal, the carrier component does not carry information and still occupies most of the power. If the transmission of the carrier component is suppressed, the power efficiency can be improved. This is called double side band with suppressed carrier (DSB for short).)
