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。
A new method of organic combination of PVT and BK to reduce the uncertainty of measurement of satellite liquid propellant is proposed. The analysis shows that the uncertainty of measurement of propellant can be reduced at the end of satellite life when the pressure is measured by high-precision and high-resolution pressure sensor To less than 2% of the total tank volume.
