Error Analysis and Improvement of Geostationary Satellites Propellant-Remaining Estimation
The end-of-life predication of geostationary satellite is mainly based on propellant-remaining estimation. The pressure-volume-temperature method (PVT) and the bookkeeping method (BK) are most popular because they are simple and feasible in engineering applications. But measuring errors are probably caused by some uncertain factors. This paper is based on a communication satellite which has been in orbit for more than 10 years; PVT and BK are applied for this satellite at the same time with a large amount of telemetry data and calculation results. To analyze and compare it, some mat hematic methods are applied, such as mean value method, comparing method, trend analysis method and so on. All these method have been applied to the practice of satellite end-of-life predication, and it was validated to improve the propellant-remaining estimation by using PVT and BK.
