任务简介

地球静止轨道运行环境卫星-U（GOES-U）是下一代地球静止气象卫星（即GOES-R系列）中的第四颗。该系列的四颗卫星提供先进成像能力，具有更高的空间分辨率和更快的覆盖速度，以实现更准确的预报、实时闪电活动测绘，并改进对太阳活动的监测。一旦GOES-U进入轨道，它将更名为GOES-19。

↗ SpaceX

The Geostationary Operational Environmental Satellite-U (GOES-U) is the fourth of the next generation of geostationary weather satellites, known as the GOES-R series. The four satellites of the series provide advanced imaging with increased spatial resolution and faster coverage for more accurate forecasts, real-time mapping of lightning activity, and improved monitoring of solar activity. Once GOES-U reaches orbit, it will be renamed GOES-19.
