Data expansion

Leo satellite system generally refers to a large-scale satellite system composed of multiple satellites that can process real-time information, and the distribution of satellites is called satellite constellation. LEO satellites are mainly used for military target detection. It is easy to obtain high-resolution images of targets by using low-orbit satellites, and it is also used for mobile phone communication.

The low orbit height of LEO satellites makes the transmission delay short and the path loss small. The communication system composed of multiple satellites can achieve real global coverage, and frequency reuse is more effective. LEO satellite constellation consists of multiple satellites in multiple orbits. Because LEO satellites are not synchronized with the Earth, the constellations are constantly changing, and the relative positions of satellites are also constantly changing.

In order to manage and realize the real-time communication of multi-satellite system, satellites should not only be connected with ground terminals and gateway stations, but also be connected with each other. Technologies such as cellular communication, multiple access, spot beam and frequency reuse also provide technical support for LEO satellite mobile communication. LEO satellite is the latest and most promising satellite mobile communication system.
