摘要:
针对地震发生后对受灾地区高精度地图的获取需求,考虑到静止轨道轨位的紧张性,研究了一种基于共位衍射的卫星成像系统。该系统由两颗共位卫星构成,一颗为成像卫星,另一颗为薄膜衍射卫星,相比于传统的单颗成像卫星,该系统具有响应迅速以及空间分辨率高的优势。本文基于共位策略和隔离策略相结合的设计原则,采用倾角/偏心率协调隔离的方法,设计了一组轨位在10.6E定点经度内的共位衍射成像系统轨道根数。通过仿真分析,将各个共位卫星之间相对距离与实际在轨卫星的相对距离做对比,仿真结果与实际数据间的误差满足一定的设计要求。因此,该组轨道根数在实际在轨应用中具备一定可行性,本文设计的共位衍射卫星系统为灾后应急响应提供重要参考。
Abstract:
Aiming at the need of high precision map acquisition of the disaster area after earthquake and considering the tense of the geostationary orbit, animaging system based on the co-location diffraction is studied. The system consists of two co-location satellites, one is an imaging satellite and the other is a thin-film diffraction satellite. Compared with the traditional single imaging satellite the new system has the advantages of quick response and spatial resolution. Based on the design principle which are combined of the co-location strategy and the isolation strategy, a group of orbital elements of the co-location diffraction imaging system within the fixed point longitude of 10.6E were designed by using the Inclination/eccentricity coordination isolation method. In the end, the relative distance between the two co-location satellites are simulated. Compared the simulation result with the actual data of on-orbit system, the error can satisfy the design request. In summary, the designed orbital elements have the feasibility in actual application, and the co-location diffraction satellites system can provide reference for fast response after earthquake.
