请高手帮我翻译一下一段摘要，要求：
1.别直接用在线翻译软件翻译，要考虑到专业词汇
2.语法一定要正确，尽量使得翻译很通顺

20世纪50年代以来，空间技术不断发展，航天器根据应用领域不同，发展形成了通信、气象、导航、资源环境、军事侦察、科学研究等系列，并向高性能、高集成方向发展。多个小型空间飞行器通过编队协同工作来实现一个大型空间飞行器的功能，将更具有经济性、灵活性、可靠性以及可以实现更强大的功能等优点。因此，空间飞行器的编队飞行已成为近年来航天领域研究的热点之一。

要对两个飞行器在空中的相对运动进行抽象建模，首先从最基本的编队飞行的概念、优势以及目前国内外在该领域的发展情况等进行了解，而文中涉及到对抽象模型的仿真，所以很有必要对仿真的基础知识进行了解。

其次，对建模过程中所涉及的运动学、动力学以及姿态描述方法等知识进行阐述，依据参考文献，对一部分内容进行扩展性推导。在几种常用的姿态描述方法中，明确各种方法的优缺点，同时注意其约束条件。

最后，建立的模型中是考虑两个飞行器之间的相对运动，导出通用的六自由度运动方程。以仿真软件Matlab中的Simulink模块为仿真平台，对该相对运动场景进行设置，完成仿真后对仿真结果进行分析，确定建模方程的适用性及使用约束性。

Answer 1

Since in the 1950s of the 20th century, continuous development of space technology, spacecraft under application are different, the development of the formation of communications, meteorological, navigation, resources and environment, and military surveillance series of scientific research and high performance, highly integrated development. A number of small - sized spacecraft through cooperative work to realize the function of a large - scale space vehicle, will be more economical, flexibility, reliability, and you can implement more powerful function of advantages. therefore, the spacecraft formation flying in recent years has become one of the hot spots of space research. On the relative motion of two aircraft in the air of abstraction modeling, first of all from the most basic concepts of formation flying, advantages and development at home and abroad in the fields such as understanding, which involves abstract model simulation, so it is necessary to understand the basic knowledge of simulation. secondly, on the kinematics of modeling involved in the process, dynamics and the attitude description method of knowledge addressed, according to the reference literature, to some extend deduction. In several common attitude description, clear advantages and disadvantages of the various methods and their constraints. finally, the establishment of a model is relative motion between the two aircraft, export six - degree - of - freedom equations of motion of universal. Simulation of Simulink in Matlab software module for simulation platform, set the relative motion of scenario, after completing simulation analysis to Simulation results, determine the applicability and use of model equation constraints.

Answer 2

Since the 1950s, space technology development, according to the different applications, spacecraft development formed communication, meteorology, navigation, resources and environment, the military reconnaissance, scientific research, and to the series of high performance, high integration development direction. Multiple small space flight through collaborative work to achieve a squadron of large space vehicles, the function is more economical, flexibility and reliability and can realize more powerful function, etc. Therefore, space flight formation flight in recent years has become a hot topic in the space.

Two aircraft in the air to the relative motion abstraction, begin from the basic model of the concept, the advantages of formation flight in this field both at home and abroad, and the development of understanding, but this involves to the abstract model of simulation, so it is necessary to understand the basic knowledge of simulation.

Secondly, in the process of modeling involves kinematics and dynamics and gesture description method based on knowledge, references, and part of the content of this paper. Expansibility In several common posture in the description method, advantages and disadvantages of various methods, and note its constraints.

Finally, the model is considered the relative movement between two aircraft, general six degrees of freedom movement equation. By simulation software Matlab simulation platform for the Simulink module, the relative motion simulation, complete set scene of simulation results after analysis, modeling equations using applicability and binding.

Answer 4

Since 1950s, the space technology has been in its blooming time, and there have been many kinds of spacecrafts based on its application area, such as communication, weather, navigation, resource&environment, military reconnaissance, science research, and etc.Multiple small space flight through collaborative work to achieve a squadron of large space flight,then it would be more economical, flexibility and reliability and can realize more powerful function, etc.Therefore, the spacecraft formation flying has become a hot research field in recent years, one of space.

In order to abstract and modeling about two aircraft relative moving in the air,firstly,we need to start with the basic concept of aircraft formation flying, its advantages, and current domestic and international developments in this field to understand,.While the paper relates to the abstract model of the simulation, so it is very necessary to understand the basics of simulation.

Second,the paper will state the basic concepts involved in the process of modeling based on reference and derive the partial content ,such as the kinematics, dynamics, and the methods of attitude representations.To the several methods of attitude representations,we should specify the advantages and disadvantages of each method, bearing in mind the constraints.

Finally,the paper will elicit the general equations of motion about six-DOF,considering the relative motion between the two aircraft.By using of the siumlation software,the paper will set the scene about the relative motion in Matlab/Simulink,after the completion of simulation to analyze the simulation results to determine the applicability of model equations and the restraints.
