摘　　要：针对天文卫星观测数据分散、完整质量信息获取难的问题,文章提出一种基于多层数据信息综合判断天文卫星数据质量的方法,首先判断传输帧层、源包层数据的连续性;然后从载荷包层判断一组观测数据的完整性,联合生成数据质量信息。经爱因斯坦探针(EP)卫星地面数据处理业务系统应用,在轨测试数据验证结果表明:该方法能够准确获得EP卫星数据质量判断结果,可以为后续天文卫星数据质量判断提供参考。Aiming at the problems of scattered astronomical satellites observation data and the difficulty in obtaining complete quality information,a method for comprehensively judging the data quality of astronomical satellites based on multi-layer data information is proposed in this paper.Firstly,the continuity of data at the transmission frame layer and source packet layer is judged.Then,the integrity of a set of observation data is judged from the payload packet layer,and the data quality information is jointly generated.Through the application of the ground data processing system for Einstein Probe(EP)satellite,the verification results using in-orbit test data show that this method can accurately obtain the quality judgment results of EP satellite data and provide a reference for subsequent judgments of astronomical satellite data quality.
