Route strategy of satellite network in GNSS based on topology evolution law

引用

Journal of Systems Engineering and Electronics 2014年第4期25卷 596-608页

作者： Xianqing Yi Zhenwei Hou Tao Zhong yaohong zhang Zhili Sun Science and Technology on Information Systems Engineering Laboratory National University of Defense Technology Centre for Communication Systems Research University of Surrey

As each type of satellite network has different link features, its data transmission must be designed based on its link features to improve the efficiency of data transferring. The transmission of navigation integrated services information （NISI） in a global navigation satellite system （GNSS） with inter-satellite links （ISLs） is studied by taking the real situation of inter-satellite communication links into account. An on-demand computing and buffering centralized route strategy is proposed based on dynamic grouping and the topology evolution law of the GNSS network within which the satellite nodes are operated in the manner of dynamic grouping. Dynamic grouping is based on satellites spatial relationships and the group role of the satellite node changes by turns due to its spatial relationships. The route strategy provides significant advantages of high efficiency, low complexity, and flexi- ble configuration, by which the established GNSS can possess the features and capabilities of feasible deployment, efficient transmission, convenient management, structural invulnerability and flexible expansion.

在富水软弱地层地下连续墙施工过程中,墙体接头防绕流措施是增强地下连续墙整体刚度和防渗性能,提高墙体施工质量的关键。依托佛山地铁绿岛湖中站工程,在传统防绕流措施的基础上提出新型防绕流水囊技术,通过水囊对工字钢腹板内部进行填充,封堵混凝土绕流通道,提供软弱土层临时支撑。相比传统防绕流措施,采用防绕流水囊技术后,地下连续墙浇筑速率、工字钢接头施工质量和整体防水性能显著提高。

作者： Zhenwei Hou Xianqing Yi Yue Zhao yaohong zhang Science and Technology on Information Systems Engineering Laboratory National University of Defense Technology

Autonomous navigation using an inter-satellite ranging and communication with inter-satellite links（ISL） is the trend of satellite navigation system development. By controlling the direction of phased array antenna flexibly, the directional crosslink can achieve more information from other satellites. However, the efficiency of communication is affected at the same time. In this paper, we analyse the navigation satellite network assembled directional crosslink, and then we propose a solution to describe the progress of information transmission based on building directional graph. Then we present a method of finding Earliest Journey and Shortest Journey. According to simulation result, the method we present is practicable and we also achieve some valuable conclusions.
