Abstract: In this work, the methods of flight path design, during the plane flight test, which are based on carbon satellite operating in the main plane nadir observation and the main plane flare observation mode are introduced. The condition of the flight path design methods changing caused by the observation mode parameters change due to the sun and plane movement are fully considered in this method. The flight path design requires three essential procedures, namely, a flight path design models, a flight path design criterion and the definite design results. By comparing the calculated data with the actual calibration flight test data, this method is proved to be effective and accurate by the error analysis. The designed flight path meets the test requirements. This method is a suitable candidate for the agile target observation flight path design.

Key words: calibration flight, flight path, flight path design, agile target observation

摘要： 介绍了碳卫星工作在主平面天底观测和主平面耀斑观测两种观测模式下飞机飞行试验中航线设计方法，充分考虑了由于太阳和飞机运动所引起的观测模式参数变化而引起的飞行航线设计变化，建立了航线设计模型，给出了航线设计准则、具体设计方案及设计结果。通过对比计算数据与实际校飞试验数据，对航线设计进行误差分析，验证了航线设计方法的有效性和精确性，所设计的航线满足试验要求。该方法同样适用于其他敏捷目标观测航线设计。
