How is the live broadcast overlooking the night view of the earth done?

Using satellite remote sensing technology

With the continuous development of science and technology, the application of satellite remote sensing technology is more and more extensive, and the demand for all-round observation of the earth in various fields is increasing. How to broadcast the changes of the overall shape of the earth and the changes of objects on the earth with high accuracy is an increasingly important issue. However, the current terrestrial broadcast scheme on the market is not mature, which requires a lot of data transmission resources and hardware deployment costs, and cannot achieve accurate and smooth terrestrial broadcast effect.
