The benefits brought by space—General public versus space agencies perspectives

Space agencies and governments have been long striving to find justification for the budgets allocated to non-commercial space missions. The most frequent justifications were scientific discoveries, technological development as well as national prestige. The current study aims to have a different look at the question “Which are the benefits brought by space?” by investigating/sampling/interrogating the public opinion and identifying the perception and view of the generation that form the bulk of the taxpaying citizens for the immediate future and will be actively financing any future missions. The study focuses on the answers provided to an online survey by an international sample of population. The target individuals are in the age range of 25–44 and are users of social networks. They are either employed or students, but they are not directly involved with the space sector. The survey aims to establish whether the promotional activities of ESA, NASA and other space agencies are aligned with the perceived benefits of this sample population. Is space contributing to what the target people consider important? What could be done to improve/change this perception? How did the public perception evolve? Which are the biggest problems humanity is confronted with today according to the sample population? Could space help addressing these major problems? The paper will firstly present the statistical analysis of the sample answers and the conclusions that can be drawn from them. In a second step it will compare the perceptions and expectations of the public in regards to space with the current space agencies strategies and identify the gaps and discontinuities.

Mission-driven autonomous perception and fusion based on UAV swarm

Distributed autonomous situational awareness is one of the most important foundation for Unmanned Aerial Vehicle (UAV) swarm to implement various missions. Considering the application environment being usually characterized by strong confrontation, high dynamics, and deep uncertainty, the distributed situational awareness system based on UAV swarm needs to be driven by the mission requirements, while each node in the network can autonomously avoid collisions and perform detection mission through limited resource sharing as well as complementarity of respective advantages. By efficiently solving the problems of self-avoidance, autonomous flocking and splitting, joint estimation and control, etc., perception data from multi-platform multi-source should be extracted and fused reasonably, to generate refined, tailored target information and provide reliable support for decision-making.     

Evaluation of airborne data link communication

An experimental prototype of a cockpit data link communication interface (modified Navigation Display (ND) and Multi-purpose Control and Display Unit (MCDU)) was developed and tested in an Airbus A340 Full Flight Simulator. 8 crews (16 professional pilots) performed simulator flights in a mixed voice and data link scenario. After each experiment video recordings were presented to the pilots and they were asked to estimate subjective strain (NASA task load index) and situational aspects retrospectively. Results show an increase in subjective strain and a decrease of ‘feeling of sovereignty’ and situation awareness under data link conditions. The effect is similar to the one caused by higher workload.     

民用飞机情景识别系统试飞研究

由于平视显示器(HUD)、视景增强系统(EVS)以及合成视景系统(SVS)优秀的情景显示能力,HUD与EVS、SVS结合使用将显著提高飞行机组情景识别以及态势感知能力。同时,HUD与自动着陆系统结合使用可降低着陆和起飞时的最低天气标准。随着机组情景识别能力的提高,必须提出高效的试飞方法来验证情景识别系统的适航符合性,在分析EVS、SVS与HUD结合使用的基础上,提出综合的优化的民用飞机机组情景识别系统试飞方法以及基于任务的符合性判据。
