Space-based pseudo-fixed latitude observation mode based on the characteristics of geosynchronous orbit belt

摘要: Abstract The US Lincoln Laboratory proved that space-based visible (SBV) observation is efficient to observe space objects, especially Geosynchronous Orbit (GEO) objects. After that, SBV plays an important role in the surveillance. In this paper, a novel mode designed all GEO objects relatively short time. A low earth orbit (LEO) satellite, dawn-dusk sun-synchronous useful for observation. Thus, based on satellite. It found Pinch Point (PP) regions proposed by are spreading analysis of evolution principles As PP becoming more and widely future, many strategies it may not be any more. Hence, key point strategy design should emphasized whole belt as far possible. pseudo-fixed latitude paper characteristics belt. Unlike classical modes, makes use one-dimensional attitude adjustment reliable simple engineering, compared with gazing which needs adjust from two dimensions. includes types adjustment, i.e. daily continuous adjustment. Therefore, has characteristics. day, region fixed scanning about rectangle, while centre changes each day long term strategy. capabilities instrument 98° discussed. most can visited every almost days year using sensor 20°×2° field view (FOV). seasonal drops, caused influence shadow at equinoxes, have been overcome under mode.
