An Analysis Method of TT&C Link Based on Boosted Trajectory

航天发射测控作为遂行航天器发射的重要支撑，对保证航天器安全快速进入空间具有重要意义。基于理论弹道与姿态文件，本文设计了一种非关联火箭发射T0时刻的实时天线测控角和测控链路余量计算方案，完成自动化任意地面站跟踪条件及跟踪性能分析，生成逐秒数据输出并图像化显示。通过仿真结果分析，证实了该方法的准确性和有效性，可用于主动段测控链路分析。
As an important support for the launch of carrying spacecraft, the tracking telemetering and command (TT&C) of spacecraft launch is of great significance to ensure the safe and fast entry of spacecraft into space. A scheme of real-time antenna direction angle and TT&C link margin calculation for the time of launch of non-associated rocket based on theoretical trajectory and attitude files was proposed. Automatic analysis for any TT&C station of tracking conditions and tracking performance was completed. At the same time, data were generated per second and display was visualized. And simulation example was presented to verify the feasibility and practicability of this method. It can be used to analyze the TT&C link.
