摘要

Since the introduction of the re-orbiting requirement at end-of-life for geostationary spacecrafts, increased attention has been paid to accurate and reliable onboard propellant gauging. Several gauging systems have been developed and are in use with different degrees of accuracy and complexity. Increasing predictions on the remaining propellant allow far more efficient satellite replacement planning and might lead to a reduction of the amount of spacecrafts. rnA High Accuracy Pressure Transducer has been developed and qualified that provides a pressure reading accuracy down to two orders of magnitude better than traditional ones. The pressure transducer is a key element for the widely used pVT-methodology. rnIn addition to the improved pressure gauging technique, the measurement accuracy of total propellant consumption is mainly dictated by the prediction of propellant consumption during Liquid Apogee Engine Firing. An Ultrasonic Flow Meter has been developed and qualified that provides a direct mass flow measurement during geostationary transfer, hence represents a gain in the global propellant gauging end accuracy.
