Problems solved by technology

In "Spacecraft antennas and beam steering methods for satellite communication system" (United States Patent, Patent Number: 5642122), a similar idea is reflected, but the focus is on communication requirements rather than satellite configuration design, and the antenna system, The antenna form, antenna structure and deployment design are very different, and the realizability is extremely poor

Embodiment Construction

[0021] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0022] For satellites loaded with flat-panel phased array antennas, especially small satellites, the platform equipment is less, the equipment is highly integrated, the equipment interface is simple, and it is easy to layout and assemble. In addition, with the development of components, components are miniaturized and highly integrated, which simplifies the configuration of equipment, greatly reduces the demand for platform resources (weight, power consumption, space), and directly reduces the rigid requirements for platform structure. , making it possible to use the flat panel phased array antenna itself as a "platform structure".

[0023] The invention carries out the integrated satellite configuration design of the load platform based on the expandable flat-panel phased array antenna, cancels the traditional "building block" type platform structure and ...

Abstract

The invention discloses an integrated satellite based on an expandable flat phased array antenna. The structure of the flat phased array antenna is fully utilized as a main body of a 'platform structure', and a novel design idea is provided for a configuration design for a microwave load satellite. The satellite configuration removes the conventional platform structure, a flat phased array antennastructure is reused, which can not only greatly reduce weight, but also greatly improve the efficiency of the structure, and a load is higher. The satellite is very beneficial for the design of satellites.

Description

technical field [0001] The invention belongs to the technical field of overall satellite design, and in particular relates to an integrated satellite based on an expandable flat-panel phased array antenna. Background technique [0002] The satellite configuration refers to the overall basic space structure and form of the satellite, and the overall spatial layout, shape and outline size that meet the different requirements of the satellite's entire life cycle from development, launch, operation to return (for returnable satellites). The design of satellite configuration is mainly constrained by several factors: payload, orbital characteristics, attitude control method and launch vehicle, etc. Among them, the payload is the dominant factor, and the configuration of the satellite must meet the requirements of the payload. [0003] In the current satellite configuration design, a certain platform is usually selected, and the platform structure is the main body, and the microwa...
