任务简介

首颗气象系统后续(WSF)卫星。 WSF-M(气象系统后续-微波)是美国国防部(DoD)的下一代业务环境卫星系统,用于替代DMSP卫星的微波波长天气预报能力。 2017年11月下旬,Ball Aerospace被选为2颗低地球轨道(LEO)气象卫星的主承包商,搭载被动微波成像辐射计仪器和由空军研究实验室开发的政府提供的能量带电粒子(ECP)传感器空间天气有效载荷。该辐射计利用了Ball制造的全球降水测量(GPM)微波成像仪(GMI)仪器。 该任务将通过全球测量大气和海洋表面,改善海洋区域的天气预报。

First Weather System Follow-on (WSF) satellite. WSF-M (Weather System Follow-on - Microwave) is the next-generation operational environmental satellite system for the Department of Defense (DoD), to replace the microwave wavelength weather forecasting capabilities of the DMSP satellites. Ball Aerospace has been selected in late November 2017 to be the prime contractor for 2 Low Earth Orbit (LEO) weather satellites with a passive microwave imaging radiometer instrument and hosted Government furnished energetic charged particle (ECP) sensor space weather payload developed by the Air Force Research Laboratory. The radiometer leverages the Ball-built Global Precipitation Measurement (GPM) Microwave Imager (GMI) instrument. This mission will improve weather forecasting over maritime regions by taking global measurements of the atmosphere and ocean surface.
