Abstract

The invention provides a beam control method, a low-earth-orbit satellite, a LEO satellite system and a computer readable storage medium, and relates to the technical field of satellites. The beam control method comprises the following steps that the LEO satellite performs on-off control on a transmitting beam, wherein the transmitting direction of the started transmitting beam is a first direction, the direction in which a high-earth-orbit (HEO) satellite transmits signals to a user terminal covered by the started transmitting beam is a second direction, and an included angle between the first direction and the second direction is greater than the minimum isolation angle between the LEO satellite and the HEO satellite. A beam coverage area is adjusted through on-off control of the LEO satellite on the transmitting beam, and interference between a LEO satellite communication system and a HEO satellite communication system can be reduced.

Description

technical field [0001] The present disclosure relates to the field of satellite technology, and in particular to a beam control method, a low-orbit satellite, a low-orbit satellite system, and a computer-readable storage medium. Background technique [0002] In recent years, the low-orbit satellite communication system has become a new growth point in the field of satellite communication. The low-orbit satellite communication system usually consists of a constellation of communication satellites with an orbital altitude of 300 to 1,500 kilometers and supporting ground systems and other system equipment. The user access terminal transmits wireless signals, which are received by the receiving antenna of the low-orbit communication satellite and forwarded to the ground system to access the ground network. At the same time, the low-orbit communication satellite transmits the signal returned by the ground system to the user terminal through the satellite transmitting antenna to ...
