摘要/Abstract

摘要： 提出了一种ＰＶＴ和ＢＫ有机结合以降低卫星液体推进剂测量不确定度的新方法，通过分析说明了当应用高精度高分辨压传感器测量压力时，卫星寿命末期推进剂测量不确定度可降低到贮箱总体积的２％以下。

Abstract: It was proposed that a new way to reduce the measurement uncertainty of liquid propellant on satellite in orbit by combining PVT with BK organically.That the uncertainty at satellite end of life is about 2% of the tank volume was also identified with uncertainities analyses in detail,when a high accuracy and high resolution pressure transducer was applied for pressure measurement.
