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。
关键词: 卫星运行管理;液体推进剂;推进剂剩余量;精密测量;误差控制
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.
Key words: Satellite operation management;Liquid propellant;Propellant residual;Becision measurement;Error control
