Space-Based Observation Mission Research Of GEO Targets

With the rapid development of space industry, relevant technology of space-based space surveillance is becoming more and more mature.It is becoming possible to use space-based observation satellite to track the spatial localization of target and realize space situation. Under such background, this paper firstly summarizes the current development of space-based space surveillance, and then analyzes the demand of the whole space observation. Tracking the needs of these observations, this paper mainly studied the observatory strategy and evaluated the effect based the catalog space target database.designed a selection sche me of space targets close approach and solved several key problems. First established observable close approach as three goals approaching mathematical model. By problem decomposition, we made this problem into multiple two targets close problems. Then based on the existing analysis method and reasonable planning of select steps, we successfully solved the problem that the compute time is too much. Finally, the simulation show that the filtering scheme is efficient and feasible.GEO targets distribution analysis. Studing GEO targets distribution is a theory preparation to make the GEO targets observation strategy more reasonable and efficient. Based on the GEO target individual perturbed motion, This paper paied attention on the whole evolution rule of GEOtargets. Through the combination of theoretical derivation and actual data,we verified the fluctuation characteristics and the specific form of GEO targets "celestial track " envelope.Formulation and evaluation og GEO observation strategy. Firstly, we contrasted and summarized advantages and disadvantages and limitations of GEO observation strategy that commonly used at present. Based on the analysis and fluctuation characteristics of GEO targets "celestial track" envelope, we proposed a observation strategy that can cover all the GEO targets and analyzed the key problems.
