冻结轨道及其应用

近来在对地观测卫星系统的设计中越来越多地采用冻结轨道,因为它能使卫星(作为一个质点)在不同时刻通过同一纬度时具有相同的运动特性,这就使得卫星在不同时刻经过同一地区所得到的遥感图片具有相同的几何特性。本文详细地讨论了冻结轨道条件、性状及其应用

FROZEN ORBIT WITH ITS APPLICATION

In the design of the earth observation satellite system the frozen orbit is playing more and more important rule recently. This is because it can provide satellites (as-mass points) with same dynamical conditions when satellitc passes through same latitudes at different times, so that remote sensing images of same areas taken at different times have same geometric feature. In this paper conditions and features of the frozen orbit are studied in detail with its applications.
