Moon-based visibility analysis for the observation of "the Belt and Road"

Abstract

Aiming at promoting the economic prosperity and regional economic cooperation, the "Silk Road Economic Belt" and the "21st Century Maritime Silk Road" (hereinafter referred to as the Belt and Road) was raised. To get a better understanding of "the Belt and Road" whole region, considering the large-scale characteristic, the Moon platform is a good choice. In this paper, the ephemeris is taken as data source and the positions and attitudes of Sun, Earth and Moon are obtained based on the reference systems transformation. Then we construct a simplified observation model and calculate the spatial and angular visibility of the Moon platform for "the Belt and Road" region. It turns out that Moon-based observation of this region shows a good performance of spatial visibility and variable angular visibility, indicating the Moon being a new potential platform for large-scale Earth observation.
