Multidisciplinary earth observation satellite optimization system on basis of enveloping dual-algorithm system

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.
