Problems solved by technology

Considering the characteristics of the feeder link, the feeder antenna often adopts the mechanical scanning form of the servo reflector. Due to the constraints of the satellite configuration and layout, the installation positions of the two antennas are usually relatively close. When relay tracking the gateway station, the servo of the two antennas Reflecting surfaces are easy to block each other, resulting in a decrease in antenna efficiency

Abstract

The embodiment of the invention discloses a low-orbit satellite feed antenna layout and switching method, computer equipment and a medium, in one specific embodiment, the method comprises the steps that two pairs of feed antennas are made to be arranged front and back in the flight direction of a low-orbit satellite, the feed antenna located in the front tracks a gateway station located in the front in the flight direction, and the gateway station is located in the back in the flight direction; the rear feed antenna tracks the gateway station located behind the flight direction; the included angle alpha between the projection of the feed link vector under the orbital coordinate system and the satellite velocity vector is calculated on the satellite in real time, and when alpha is larger than or equal to 90 degrees, it is considered that the satellite flies over the current gateway station, and switching of the two feed antennas is carried out: in the switching strategy, a front-back switching strategy is adopted, the feed antenna located behind tracks the current gateway station in a relay mode, and the satellite velocity vector is switched to the current gateway station in a relay mode; the front feed antenna is aligned with the next gateway station in front of the flight direction; wherein the current gateway station is a gateway station tracked by the front feed antenna at the current moment.

Description

technical field [0001] The present invention relates to the field of electronic communication. More specifically, it relates to a low-orbit satellite feed antenna layout and switching method, computer equipment and medium. Background technique [0002] With the rapid development of wireless communication technology, antennas, as indispensable components in various wireless communication devices, have gained wide application and important technological progress. [0003] The feed antenna of the communication satellite needs to exchange information with the ground gateway station. Since the relative positions of the low-orbit communication satellite and the ground gateway station are constantly changing, to achieve uninterrupted communication, two antennas are required to work alternately. Considering the characteristics of the feeder link, the feeder antenna often adopts the mechanical scanning form of the servo reflector. Due to the constraints of the satellite configuratio...
