摘要/Abstract

摘要：

随着在轨航天器数量急剧增长,地面测控资源调度成为一个越来越复杂的系统工程问题。当前地面测控资源调度效能评估仍停留在人工统计数据、孤立指标评价的层次上,这些零散的指标比较片面且难以综合反映测控资源调度能力,缺乏科学合理的综合效能评估指标体系。基于地面测控资源调度实际情况,在研究确定测控资源调度评估指标要素的基础上,构建了分层、多维的测控资源调度效能评估指标体系,为后续资源调度效能评估提供了依据,促进了地面测控资源调度的不断优化。

Abstract:

With the rapid increase in the number of orbiting spacecraft, ground-based telemetry, track and command (TT&C) resource scheduling has become an increasingly complex system engineering problem. At present, the effectiveness evaluation of ground-based TT&C resource scheduling still stays at the level of manual statistical data and isolated index evaluation. These scattered indicators are relatively one-sided and difficult to comprehensively reflect the ability of TT&C resource scheduling, and there is lack of scientific and reasonable index system about the comprehensive performance evaluation. Based on the actual situation of ground-based TT&C resource scheduling, a hierarchical and multi-dimensional effectiveness evaluation index system of the TT&C resource scheduling based on the research and determination of TT&C resource scheduling evaluation indicators is constructed, which provides a basis for the subsequent evaluation of resource scheduling effectiveness and promotes the continuous optimization of ground-based TT&C resource scheduling.

Key words: telemetry, track and command (TT&C) resource scheduling, evaluation index system, analytic hierarchy process
