The S06 Session Autonomous Navigation and Intelligent Operation was Held
On May 28, 2021, the 12th China Satellite Navigation Conference S06 Session Autonomous Navigation and Intelligent Operation was held in Conference Hall 203, Primus Hotel Nanchang International Expo City, Jiangxi. The Session started with the introduction about the chairmen of S06 Session, given by Member of CSNC Organizing Committee--Zheng Jinjun. The Sub-session 1 was chaired by Prof. Zhan Xingqun of Shanghai Jiao Tong University. Other chairmen of the Session include Researcher Wang Haihong of China Academy of Space Technology, Researcher Gong Wenbin of Innovation Academy for Microsatellite, Chinese Academy of Sciences, Researcher Hu Caibo of Beijing Satellite Navigation Center, Prof. Zhao Yuxin of Harbin Engineering University and Prof. Naser El-Sheimy of University of Calgary, Canada. Professor Naser El-Sheimy of the University of Calgary (Canada) served as co-chairs. Researcher Zheng Jinjun from China Academy of Space Technology introduced the Session’s focus on the prospects for autonomous navigation and intelligent operation at the system level and application level.
Autonomous navigation refers to the path planning and autonomous execution of a carrier (such as a vehicle) without human intervention. In recent years, with the rapid development of autonomous driving technology and autonomous robots, the demand for autonomous navigation has become more and more urgent, making autonomous navigation an important development direction for navigation systems. The 12th China Satellite Navigation Conference "S06: Autonomous Navigation and Intelligent Operation" Session is focused on the academic exchanges related to advanced positioning and navigation algorithms. Based on the fusion of multi-source information and the characteristics of application scenarios, the Session explores the optimal solution to highly autonomous navigation and intelligent operation systems, which provides technical reference for the development of autonomous navigation and intelligent operation. The topics of the Session include: reliability of autonomous navigation, multi-source information fusion, cooperative navigation and intelligent system operation. Relevant algorithms, methods and tests imvolved in multi-sensor fusion systems based on GNSS, inertial sensors, odometer, geomagnetometer, radar, LIDAR, camera, barometer, maps, signals of opportunity, infrared and ultrasonic sensors etc were explored.
The Session lasts one and a half days, with a total of 28 presentations. Four sub-sessions were held on the first day of the Session. The first and second sub-sessions were about the reliability of autonomous navigation. The Session invited Dr. Chen Jie of Qianxun SI Network Co., Ltd to give a presentation on the theories and practices related to functional safety of navigation system. Dr. Chen started his academic sharing by focusing on several aspects such as the goals and common standards of functional security, the importance of functional security of navigation system in autonomous navigation and intelligent operation, common implementation logic of functional safety and talked about his understanding of functional safety based on Qianxun’s practices in functional security compliance. Zhai Yawei, Winner of CSNC Outstanding Paper Award, gave a presentation entitled “Analysis and Mitigation of Visual Navigation Vulnerability Mechanisms”. Dr. Zhai analyzed the real-time detection of visual navigation vulnerability from the perspectives of definition and root causes of visual navigation vulnerability, proposed three vulnerability detection methods, and explained the concept of visual navigation vulnerability based on insufficient navigation accuracy warning, mismatching warning and poor image quality warning. Li Qipeng from Wuhan University, Wang Yue from Shanghai Jiao Tong University, Wang Yuqi from the 20th Research Institute of China Electronics Technology Group Corporation, Wang Junshuai from Space Star Technology Co., Ltd, Wang Jian from China Academy of Space Technology and Ding Yiming from Nanjing University of Aeronautics and Astronautics made excellent presentations on the reliability of autonomous navigation. The Sub-session 3 deals with the topic of cooperative navigation. Prof. Xiong Zhi from Nanjing University of Aeronautics and Astronautics was invited to give a presentation on “Development and Application Prospects of Unmanned Cluster Intelligent Navigation”, which introduced unmanned cluster technology by giving an overview of unmanned cluster system and elaborating on the system’s development, biological navigation and brain-like intelligent navigation, and brain-like intelligent navigation research and applications, analyzed the problems of unmanned clusters, explanined the technology of biological navigation, and looked forward to the future development of unmanned clusters. Zeng Lingchuan from Institute of Optoelectronics, Chinese Academy of Sciences and also the Second Prize Winner of CSNC Outstanding Youth Paper Award and Wang Dongmin from Information Engineering University shared their research results on the strategies for selection of nodes of sky-based network of navigation satellites and cooperative positioning algorithms respectively.
In terms of the highly reliable autonomous navigation topic disscussed during Sub-session 4, Zhang Jiong from COMAC Beijing Aircraft Technology Research Institute was invited to elaborate on the demand for unmanned autonomous navigation in urban air traffic scenarios. Mr. Zhang also put forward the UAM concept and the demand for autonomous navigation, introduced intelligent connectivity management, and looked forward to the future of autonomous navigation together with other participating representatives. Jia Weisong from General Department of China Academy of Space Technology made a presentation on the design and validation of the long-term reliable autonomous navigation system for navigation satellites, and Xing Bowen and M Sakr from the 54th Research Institute of China Electronics Technology Group Corporation made relevant presentations on wearable autonomous positioning and navigation and multi-sensor fusion technologies.
In terms of the multi-source information fusion topic discussed during Sub-session 4, Wu Yuanxin from Shanghai Jiao Tong University was invited to give a presentation entitled “Vehicle Navigation Technology in Satellite Denial”. Prof. Wu started by sharing the vehicle navigation issues, background and needs and then analyzed the problems related to combined inertial and odometer navigation. Kuang Jian from Wuhan University, Yang Tao from Beijing Jiaotong University, Wang Ruochen from Shanghai Jiao Tong University, Lv Qiaochu from National University of Defense Technology and Luo Yarong from Wuhan University make detailed presentations on slam, combined navigation and other related issues.
The Sub-session 5 and Sub-session 6 deal with the topic of intelligent system operation. Chen Jinping from Beijing Satellite Navigation Center was invited to give a presentation entitled “Some Thoughts on Building an Intelligent Operation and Control System”. Chief Engineer Mr. Chen offered the technical analysis by explaining the characteristics and architecture of GNSS system, BDS operation and maintenance tasks and difficulties and the thoughts on the introduction of intelligent operation and maintenance methods into the operation and control system. Wang Haihong, Zhuang Jianlou and Chen Qiuli from China Academy of Space Technology, Li Xiaoyue and Huang Zheng from Innovation Academy for Microsatellites of Chinese Academy of Sciences, Lei Lei from Xi’an Satellite Control Center, Yao Jintao from the 20th Research Institute of China Electronics Technology Group Corporation and Tang Jingshi from Nanjing University made related presentations based on the topic.
