Ground data transmission antenna layout method adapting to inter-satellite transmission

Abstract

The invention provides a ground data transmission antenna layout method adapting to inter-satellite transmission. The method comprises the following steps: firstly, determining the requirements of a data transmission antenna on an on-orbit operation satellite for ground and inter-satellite data transmission, secondly, determining the installation position and the axis direction of the data transmission antenna on the on-orbit operation satellite, and finally, determining the connection mode of the data transmission antenna and the on-orbit operation satellite to ensure that the data transmission antenna is not shielded. According to the method provided by the invention, the problems that in the process of multiple satellites fly along and fly around in constellation networking, beam shielding of an on-orbit semi-airspace inter-satellite data transmission antenna of a satellite, interference between the data transmission antenna and a ground load and a solar array, and the narrow configuration layout of a space in a fairing during launching are solved. The beneficial effects of half-airspace data transmission, multi-component interference elimination and adaptation to the internalspace of the fairing are achieved, a selection mode with high expansion capacity and high applicability is provided, and high universality is achieved.

Description

technical field [0001] The present invention relates to space vehicle configuration and layout design, ground and on-orbit communication signal data transmission, and multi-constraint system integration and compatibility technologies. Specifically, it relates to a ground-to-ground data transmission antenna layout method suitable for inter-satellite transmission, especially to A layout method for ground-to-ground data transmission antennas on a satellite that satisfies the internal accommodation space of the launch vehicle fairing and meets the requirements of inter-satellite data transmission. Background technique [0002] In the future, spacecraft will develop in the direction of large-scale, multi-functional, performance expansion and high integration. The salient features of these spacecraft in the process of configuration and layout mainly include: larger size envelope requirements, wider detection range, more prominent interference and occlusion problems, and layout opt...

Problems solved by technology

[0005] As in-orbit applications such as high and low orbit satellites and constellation networking continue to be proposed in the field of communication, the existing data transmission antenna single-to-ground communication signal transmission capability is no longer suitable for multi-satellite flying around, accompanying flying to the front and rear, left and right sides, and inter-satellite data transmission needs
