摘要
Abstract
To improve the precision of the remaining propellant gauging in space,based on the theory of gas injection method for remaining propellant gauging,a ground test of propellant gauging system is carried out.In this paper,the effect on the result of propellant gauging is analysed which is caused by the difference between the in-orbit environment and the ground one.It is confirmed that the ground test result of gas injection method can represent the precision of on-orbit implementation.The error of the temperature measure,which is caused by the difference between the on-orbit environment and the ground one,can be decreased by extending the test time and increasing the temperature measure points.关键词
