The new pulsar navigation method Significance Enhancement of Pulse-profile with Orbit-dynamics is adopted to determine the orbit with observations of only one pulsar. In this test, the Crab pulsar is chosen and observed by Insight-HXMT from 2017 August 31 to September 5. Using the five-day long observation data, the orbit of Insight-HXMT is determined successfully with the three telescopes onboard: High Energy X-ray Telescope, Medium Energy X-ray Telescope, and Low Energy X-ray Telescope, respectively. By combining all the data, the position and velocity of the Insight-HXMT are pinpointed to within 10 km (3ҩ and 10 m s-1 (3ҩ, respectively.   High power diode laser source with a transmission grating for two spectral beam combining 期刊论文  OAI收割 Optik, 2019, 卷号: 192, 页码: 4 作者:  J.Y.Tian;  J.Zhang;  H.Y.Peng;  Y.X.Lei;  L.Qin   |  收藏  |  浏览/下载：23/0  |  提交时间：2020/08/24 Diode laser,Spectral beam combining,Transmission grating,High beam,quality,array,Optics   Efficiency and Threshold Characteristics of Spectrally Beam Combined High-Power Diode Lasers 期刊论文  OAI收割 Ieee Journal of Quantum Electronics, 2019, 卷号: 55, 期号: 1, 页码: 7 作者:  F.Y.Sun;  S.L.Shu;  G.Y.Hou;  L.J.Wang;  J.Zhang   |  收藏  |  浏览/下载：35/0  |  提交时间：2020/08/24 Efficiency,laser diode array,threshold,spectral beam combining,external-cavity,Engineering,Physics,Optics
