Envisat卫星寿命延长方案对SAR数据应用的影响

Impact of the Envisat Mission Extension on SAR Data Applications

卫星的工作寿命主要取决于卫星的燃料量,一旦燃料耗尽,卫星就会失去控制而报废。根据对Envisat卫星剩余燃料的估算,欧空局将于2010年10月22日对Envisat卫星采取新措施,减少燃料消耗,以延长卫星寿命。本文主要介绍了Envisat卫星寿命延长方案对SAR数据应用所产生的影响。

The on-board hydrazine is the main limiting factor of the satellite lifetime.The satellite will lose control and out of the work when the fuel runs out.ESA proposed a technical solution for extending the envisat mission started from the 22nd October 2010,addressing the hydrazine issue based on the estimation of the fuel remained.This paper describes the impact of the envisat mission extension on SAR data applications.
