摘要
2013年9月6日,美国宇航局(NASA)发射了月球大气与尘埃环境探测器(LADEE)飞船。针对LADEE 上进行的月球激光通信演示验证(LLCD),从终端设计方面进行综述。LLCD 系统主要包括一个安装在LADEE 上的太空终端、三个地面终端以及一个协调该演示验证的地面运行中心,其中太空终端主要与一个多孔径望远镜阵列地面终端完成最高数据率为622 Mb/s 的下行链路以及最高数据率为20 Mb/s 的上行链路。考虑到该地面终端所在地的天气因素,又选择了两个备用地面终端,用来提供地理多样性,支持该演示验证。
Abstract
The US National Aeronautics and Space Administration (NASA) has launched the Lunar Atmosphere and Dust Environment Explorer (LADEE) spacecraft on September 6th, 2013. We review the terminal design of the lunar laser communication demonstration (LLCD) on LADEE, while the experiment design and development of the LLCD will be reviewed in another paper. LLCD system mainly includes one space terminal onboard, three earth-based terminals and one earth-based operation center for coordination, where bidirectional laser communications are mainly performed between the space terminal and the multi-aperture telescope array earth-based terminal at downlink data rates up to 622 Mb/s and uplink up to 20 Mb/s. When the weather is considered, two additional earth-based terminals, as back-ups for support, provide geographic diversity.
