Abstract

The invention discloses a multidisciplinary earth observation satellite optimization system on the basis of an enveloping dual-algorithm system, and relates to multidisciplinary earth observation satellite optimization systems of enveloping dual-algorithm systems. The multidisciplinary earth observation satellite optimization system comprises five layers including a mathematical model layer L1, an optimization model layer L2, an algorithm computation layer L3, a data layer L4 and an application layer L5; the layers are in an information transmission relation which is sequentially L1-L2-L3-L4-L5. The multidisciplinary earth observation satellite optimization system has the advantages that optimization objective-earth observation resolution and interrelated constraints are determined on the basis of earth observation satellite mathematical models, satellite optimization models are built, then satellite models are optimized and computed by enveloping dual algorithms, and the optimal earth observation resolution of satellites is acquired if optimization results meet convergence criteria; the multidisciplinary earth observation satellite optimization system also can be used for quickly computing design objectives and parameter variables of the satellites, and the efficiency can be improved as compared with the traditional process including satellite designing, testing, design modifying and testing.

Description

technical field [0001] The invention provides an earth observation satellite multidisciplinary optimization system based on an envelope dual algorithm system. It is used to deal with multi-variable and multi-constraint satellite optimization problems, and can obtain the optimal earth observation resolution of earth observation satellites, which belongs to the field of aerospace technology. Background technique [0002] Nowadays, the pressure of rapid population growth and economic development is exceeding the capacity of the earth's natural system, causing abnormal climate and exhausting resources. This requires us to use satellite technology to detect resources in a timely manner. Moreover, this earth observation is the need for national defense construction and national security, such as air dominance, sea dominance, sky dominance, and information dominance. Satellite platform design is a very complex project with the characteristics of multi-discipline, multi-level and s...
