Communication Satellites provides facilitate communication quickly and reliably over long distances with a wide range through the use of radio waves. And it allows radio, television, telephone transmissions, and many others to be sent live anywhere in the world. To solve many problems like that, Communication Satellite networks are now an indispensable part of most major telecommunication systems. Satellites have a unique capability for providing coverage over large geographical areas in the way that they work with LEO orbit. For latency reduction, LEO become the most popular orbit for researchers to study. In this paper, we will focus only on satellite Internet service to provide high-speed Internet via satellite to the Earth. To estimate the received signal strength at each point to get footprint coverage, we might use some software to measure the received signal at each point to verify and modify the model by calculating and looking for the footprint coverage of communication satellites in Cambodia. To find all these problems in projects, we have been using some tools for testing and implementing the way that satellites and the Earth rotate. Like MATLAB software for analysis, and calculation of the link budget for the propagation model. As optional, we also use a professional space-analysis software satellite Tool kit AGI’s STK for visualization.
