Abstract： In the field of satellite communications， the research on low-orbit satellite mobile communications has been a hot spot in recent years. With the increase of mobile users， strengthening the management of mobile communications by determining the user's location can effectively reduce the operating load of the system. This article will analyze the beam closing method of the low orbit satellite based on the user's location by constructing a low-orbit satellite and multi-beam model， and explore the feasibility of the beam closing method of the low-orbit satellite based on the user's location based on the analysis results.

Key words： user location; low-orbit satellite communication; beam off
