| description | The invention discloses a remote sensing satellite sun synchronous orbit design method based on revisit characteristics. The relationship between revisit and ground synchronization is established through a Q value. Starting from the determined interval, a mathematical model of Q is established through a node revisit sequence, and then the coverage rate is obtained through the track height and observation angle mixed node access sequence and the coverage area. And finally, the coverage rate of the remote sensing satellite on the sun synchronous orbit is displayed in three aspects of the time-varying coverage rate, the minimum coverage time and the minimum observation angle, so that a reference is provided for the design of the sun synchronous orbit of the remote sensing satellite.
一种基于重访特性的遥感卫星太阳同步轨道设计方法，通过Q值建立了重访和地面同步之间的关系。在确定的区间出发通过节点重访顺序建立了Q的数学模型，再通过轨道高度和观测角度混合节点访问顺序和覆盖面积得到覆盖率。最后通过时变覆盖率、最小覆盖时间和最小观测角度，三个方面展示遥感卫星在太阳同步轨道上的覆盖率，从而为遥感卫星太阳同步轨道的设计提供了参考。 |
