    • A method for operating a satellite (10, 34) so that a predetermined amount of propellant is left to perform end-of-life maneuvers is provided. A first pressure differential is established between a first propellant tank (74) and a second propellant tank (76) by pressurizing the first tank (76) with a pressurant. Propellant is transferred from the first tank (74) to the second tank (76). Using precise control during transfer the amount of propellant in the tanks may be determined. The second tank is used for orbit maintenance. The first tank is used for end-of-life maneuvers. Propellant may be transferred between the tanks using a latching process so that a predetermined amount of propellant may be transferred from a non-empty tank to a full tank.
    • 提供了一种用于操作卫星(10,34)以便留出预定量的推进剂来执行报废机动的方法。 通过用加压器对第一罐(76)加压,在第一推进剂罐(74)和第二推进剂罐(76)之间建立第一压力差。 推进剂从第一罐(74)转移到第二罐(76)。 在转移期间使用精确的控制可以确定罐中的推进剂量。 第二个坦克用于轨道维护。 第一个坦克用于终身机动。 推进剂可以使用锁定过程在罐之间转移,使得预定量的推进剂可以从非空罐转移到满罐。
