这是一种尖端的太阳能电推进推力器,将用于“门户”。 (二)NASA为Astrobotic公司提供了两个导航系统,用于其CLPS飞行:导航多普勒激光雷达(Navigation Doppler Lidar),提供增强的制导和导航能力;以及地形相对导航(Terrain Relative Navigation),以提高着陆精度并帮助规避月表附近的危险。 (三)NASA选择了11家美国公司来开发...
这项技术类似于NASA的毅力号火星车系统将于2021年2月在火星上着陆时使用的技术，可以让探测器在另一颗星球上实现精确的着陆。此次飞行测试中启动的第二个传感器系统，是一个导航多普勒激光雷达（navigation Doppler lidar），由位于弗吉尼亚州汉普顿的NASA兰利研究中心（Langley Research Center）开发。这一新型传感器会使用...
蓝色起源可能因Artemis月球着陆器合同跟NASA卷入一场有争议的法律战，但这并不能阻止杰夫·贝佐斯的火箭公司安排其下一次发射。8月25日凌晨，新谢泼德号(New Shepard)将发射第17次（NS-17）任务。这将是NASA第二次月球着陆技术演示。NS-17的有效载荷旨在测试导航多普勒激光雷达(Navigation Doppler Lidar)和下降着陆计算...
today announced that it has successfully designed, qualified, and built the RIO® narrow-linewidth semiconductor laser to be used in the United States National Aeronautics and Space Administration’s (NASA) Navigation Doppler LiDAR (light detection and ranging) system. The selection of Luna’...

Doppler LidarIDECLangleyLARSSOptimized designs of the Navigation Doppler Lidar (NDL) instrument for Autonomous Landing Hazard Avoidance Technology (ALHAT) were accomplished via Interdisciplinary Design Concept (IDEC) at NASA Langley Research Center during the summer of 2013. ...
这是NASA 第二次月球着陆技术演示,“蓝色起源”在去年 10 月进行了首次技术演示。此次发射的有效载荷旨在测试导航多普勒激光雷达(Navigation Doppler Lidar)和下降着陆计算机(Descent Landing Computer)的新能力。这些系统将帮助 NASA 确定航天器降落到月球表面时的位置和速度。
NASA’s navigation Doppler lidar instrument is comprised of a chassis, containing electro-optic and electronic components, and an optical head with three telescopes. Credit: NASA The travel time and wavelength of that reflected light are used to calculate how far the craft is from the ground, wh...
Advanced Air Mobility24 Apr 2023 Plant tour: Joby Aviation, Marina, Calif., U.S. As the advanced air mobility market begins to take shape, market leader Joby Aviation works to industrialize composites manufacturing for its first-generation, composites-intensive, all-electric air taxi. ...
We have described a progression of direct detection Doppler lidar instruments beginning with the single edge aerosol lidar, followed by aerosol and molecular double edge lidar systems. These systems have been operated from laboratory and mobile ground based platforms and the newest direct detection wind...
