Tell me why satellites are closely related to our lives.

Because we provide navigation, weather forecast, communication and so on, it is closely related. Satellites are widely used. Some are equipped with photographic equipment, which can take photos of the ground, scout and investigate resources, and monitor the climate and pollution of the earth. Some are equipped with astronomical observation equipment for astronomical observation, and some are equipped with communication relay equipment to relay communication signals such as radio, television, data communication and telephone.

The role of artificial satellites

It is mainly used as a radio communication relay station in space and plays a great role in modern communication. Communication broadcasting satellite has brought many changes to human production and life. It provides us with broadcasting, television, live broadcast, mobile communication and other services, and every service cannot be separated from us. Working communication broadcasting satellites will receive radio signals from the earth or spacecraft and then amplify them.

Frequency conversion and other means are forwarded to another site to realize the transmission of information. Communication broadcasting satellite has the advantages of large coverage area, long communication distance, large transmission capacity, no limitation of terrain and environment, good communication quality, low cost and high efficiency. It is an indispensable helper in human daily life.
