Embodiment

[0042] Such as figure 1 As shown, the satellite layout design method of a kind of space-borne full airspace load of the present invention comprises the following steps:

[0043] Step 1: Analyze satellite configuration characteristics. According to the configuration of the satellite platform and payload, special attention should be paid to large unfolded parts, movable parts, and the payload head for wide field of view requirements.

[0044] Step 2: Propose design constraints for full airspace loads. Combined with the envelope of the launch vehicle fairing, analyze the safety distance margin between the existing configuration of the satellite and the fairing; according to the space margin of the satellite, put forward constraints on the design of the full airspace load, including the load system (mechanical scanning or phased array) , load envelope size, quality, quantity, etc.

[0045] Step 3: Configuration design of full airspace loads. According to the design constraints...

Abstract

The invention provides a satellite layout method and system for satellite-borne full-airspace loads. The method comprises the steps of 1, analyzing satellite configuration characteristics according tothe configuration of a satellite platform and an effective load; 2, constraining the full-airspace loads according to the satellite configuration characteristics; 3, constructing a load configurationconforming to a preset condition according to the constrained full airspace loads; and 4, based on the configuration of the existing satellite platform and the effective load, performing the satellite layout of the full-airspace loads according to the preset load configuration. According to the invention, the layout problem of full-airspace loads of different frequency bands, systems and purposeson various satellite platforms of different types is solved, the universality and the practicability are high, and support can be provided for the design of the overall satellite and related load configurations.

Description

technical field [0001] The invention relates to the technical field of satellite overall design, in particular to a satellite layout method and system for satellite-borne full-airspace loads. Background technique [0002] With the rapid development of satellite technology, satellite networking and formation missions are frequent, which puts forward higher requirements for inter-satellite communication, especially the omnidirectionality and real-time performance of inter-satellite communication. In order to meet the inter-satellite communication needs of multi-satellite cluster formations for complex configurations, and aiming at reducing on-board resource overhead, multi-satellite normalized link building, adaptive tracking and link re-establishment requirements, related complex configurations are carried out. Global inter-satellite microwave communication has become a trend. Under normal circumstances, this type of satellite will carry a payload for full-airspace communica...
