深空激光通信系统方案设计和视轴对准技术研究
Study of system scheme design and countermeasures of line-of-sight pointing in deep-space laser communication
摘要
Abstract
Scientific data return with the help of laser communication is a promising way in deep-space exploration. The United States has begun to carry out research work about deep-space laser communication (DSLC). However, our country has not yet had any reports. In this situation, the article takes Mars to earth's DSLC as the research object. According to the analysis of external constraint conditions, design principles of two important systems, which consist of the communication and APT subsystems, is proposed and in-depth design of critical parameters has been carried out. Subsequently, accurate pointing and tracking concept based on celestial body imaging is ideated. Promising scheme of DSLC is put forward for the first time in our country.关键词
