摘要
Abstract
In order to adapt to the development trend of lightweight and low-cost low earth orbit(LEO)satellites and meet the demand for rapid laser inter-satellite link establishment,a payload configuration method combining a rotatable laser payload and a fixed laser payload was adopted based on the analysis of inter-satellite laser configuration principles,used for inter-plane link establishment and intra-plane link establishment respectively.A fast inter-satellite link establishment method and process for laser payloads based on in-orbit star calibration,beacon light-assisted link establishment,and optical axis consistency design were introduced.In-orbit experimental data show that the inter-satellite laser payload link establishment time can be less than 30 s,which can achieve stable and continuous inter-satellite laser communication.The study is helpful for promoting the development and large-scale in-orbit application of inter-satellite laser communication.关键词
