基于时分复用的航天测控网卫星测控支持满足率研究
|
Abstract:
地面测控资源对卫星支持的满足率是测控网高效运行的评价尺度，是航天测控网的综合能力的重要体现。当测控网所支持的卫星数量超过一定限度时，卫星对测控资源的需求会产生冲突，某些卫星的测控需求将无法得到满足，此时测控网内地面测控资源将会出现缺口。本文基于某一测控网运行情况开展综合分析，梳理出地面测控资源的各个影响因子，建立了需求约束体系，对体系中的指标进行量化评估，通过定性、定量研究相结合的分析方法，对地面站资源的使用情况进行综合分析，从中可以初步推算出未来一段时间内地面测控资源对卫星支持的满足率，并能够据此对地面测控资源的发展规划提出合理的建议。
The satisfaction rate of ground TT & C resources to satellite support is the evaluation criterion for the efficient operation of TT & C network and an important embodiment of the comprehensive ability of Aerospace TT & C network. When the number of satellites supported by the TT & C network exceeds a certain limit, the requirements of satellites for TT & C resources will conflict, and the TT & C requirements of some satellites will not be met. At this time, there will be a gap in ground TT & C Resources in the TT & C network. Based on the operation of a measurement and control network, this paper carries out a comprehensive analysis, combs out various influencing factors of ground measurement and control resources, establishes a demand constraint system, quantitatively evaluates the indicators in the system, and comprehensively analyzes the use of ground station resources through a combination of qualitative and quantitative research, From this, we can preliminarily calculate the satisfaction rate of ground TT & C resources to satellite support in the future, and put forward reasonable suggestions on the development planning of ground TT & C resources.
