The optimization location of communication and broadcasting satellite

The optimal location of communication and broadcasting satellites in a static satellite orbit is discussed. Every country should choose the most advantageous orbit location on the limited arc-sector so that the loss of power flux density in its particular area will be lower, the receiving elevation will be higher, the receiving effect will be better, and the user´s cost will be decreased. From the viewpoint of raising receiving elevation and reducing loss of power flux density, a mathematical model of optimization location is given. The optimal satellite location for China is computed to be longitude 104.25 degrees east
