Abstract: The ground simulation test for gauging liquid propellant remaining on a satellite is introduced.The test results obtained from the isothermal model are presented in details,mainly including the transient characteristics of the pressure and temperature,the measurement accuracy and its relation with other factors.The possibility that the accuracy is better than 1% of the total tank volume is indicated,and some related problems are discussed.
