Abstract

Small satellites launching in earth Low orbit have been continuing in the past two decades. LEO satellites captured the center of attraction in the satellite communication industry due to their several advantages. Due to its faster orbital velocity, so many orbital parameters need to be considered when those satellites are in action. Despite it having many positive attributes, optimized deployment of LEO constellations is not easy. Already broadband internet is being provided by some market player which has limited coverage. This paper investigates the coverage geometry of LEO Constellations and their subsequent implementation. Current trends, challenges, and future direction of LEO Constellations are discussed here. Due to the advancements in Inter Satellite Link Intra Satellite Links, Free space Optical communication paved the way to optimizing its coverage. With regards to LEO satellite altitude, how the elevation and azimuth angle changes were had simulated. Current trends, challenges, and future direction of LEO Constellations are discussed here.

多层LEO卫星星座覆盖分析及当前研究方向

近二十年来，在近地轨道上发射小卫星一直在继续。近地轨道卫星以其多种优势成为卫星通信行业的焦点。由于它的轨道速度更快，所以这些卫星在运行时需要考虑许多轨道参数。尽管它有许多积极的属性，但LEO星座的优化部署并不容易。一些市场参与者已经提供了宽带互联网，但覆盖范围有限。本文研究了低轨道星座的覆盖几何及其后续实现。本文将讨论狮子座星座的当前趋势、挑战和未来方向。由于卫星间链路卫星内链路的进步，自由空间光通信为优化其覆盖铺平了道路。针对低轨卫星高度，模拟了低轨卫星的仰角和方位角变化情况。本文将讨论狮子座星座的当前趋势、挑战和未来方向。
