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.   a low power adaptive clock and data recovery circuit for wireless implantable systems 期刊论文  OAI收割 Shenzhen Daxue Xuebao (Ligong Ban)/Journal of Shenzhen University Science and Engineering, 2011, 卷号: 28, 期号: 2, 页码: 143-146 Yu Hang; Li Yan; Jiang Lai; Ji Zhen; Yan Ping-Kun; Wang Fei   |  收藏  |  浏览/下载：16/0  |  提交时间：2013/10/08 Charge pump circuits  Clocks  CMOS integrated circuits  Design  Electric power supplies to apparatus  Input output programs  Integrated circuits  Jitter  Metallic compounds  MOS devices  Optical pumping  Packet switching  Pulse modulation  Pulse position modulation  Pumps  Transistors   基于LDPC与PPM的水下高速光通信系统设计 学位论文  OAI收割 作者:  米乐   |  收藏  |  浏览/下载：31/0  |  提交时间：2018/12/26 水下光通信  underwater optical communication  LDPC编码  low-density parity check codes  PPM调制  pulse position modulation  蒙特卡洛  Monte Carlo method
