摘要: 該文對(duì)編隊(duì)飛行小衛(wèi)星的星間鏈路幾何特性(方位角、仰角及星間距離)進(jìn)行較為深入的研究。在提出橢圓軌道下編隊(duì)小衛(wèi)星星間鏈路幾何特性的計(jì)算公式后，結(jié)合實(shí)例做了相應(yīng)的仿真，并對(duì)仿真結(jié)果進(jìn)行了進(jìn)一步的討論，得到了星間鏈路幾何特性隨軌道參數(shù)變化的規(guī)律。對(duì)于未來(lái)星座設(shè)計(jì)、編隊(duì)小衛(wèi)星組網(wǎng)等方面具有較大的參考價(jià)值。

Abstract: This paper focuses on the geometrical properties of Inter-Satellite Links (ISLs) of the small satellites formation flying under the elliptical orbits, including the azimuth, elevation and the distance. The article addresses the mathematical formula for these characteristics., and then presents the simulation results based on the given example. The paper also analyzes the law that the formation flyings ISLs geometrical characteristics change with the parameters of the satellite constellation. These results are important for futures constellation design , satellite networking, etc. -
