航天器故障诊断和预测天地一体化集成系统

在轨航天器和地面航天飞控中心天地2个系统缺乏相互支持和配合，是导致对航天器故障诊断和预测能力不足的重要因素之一。为了提高航天器故障诊断和预测的有效性、可靠性和准确性，需要将天地2个系统集成为一个整体（天地一体化系统）。设计了航天器故障天地一体化集成诊断和预测系统，讨论了航天器故障天地一体化集成诊断和预测方法，对航天器故障天地一体化集成诊断系统和方法的特点进行了分析。将天地2个系统集成在一起对航天器故障进行诊断和预测，其效率、准确性和可靠性较高。

Fault Diagnosis and Prediction System for In-orbit Spacecraft Based on On-board and Ground Integration

Lack of supporting and cooperating between on-board and ground system is one of the key factor resulting in lower ability to diagnose an.d predict the faults of spacecraft in orbit. In order to change the situation, the two systems should be integrated into one system （on-board and ground integrated system）. Here, the integrated system is designed, and method used by the integrated system is proposed. The features of the designed system and proposed method are analyzed. For diagnosing and predicting the faults of spacecraft, it is more effective to use the integrated system than use on-board system or ground system only.
