Problems solved by technology

[0002] With the development of live satellite broadcasting and TV broadcasting, more and more users use live satellite set-top boxes to watch programs, that is, receive signals from satellite receivers through set-top boxes. However, it is difficult for ordinary users to install live satellite receivers. The thing is that when installing the receiving pot, it is necessary to accurately locate the longitude and latitude of the Zhongxing-9 satellite. Under the current technology, the user needs to manually adjust the direction of the satellite receiving pot for positioning. Signal, not only difficult, but also very inconvenient
