NOAA 的 GOES-U 完成太阳能阵列部署测试

NOAA 的 GOES-U 完成太阳能阵列部署测试


GOES-U 是NOAA GOES-R 系列中的第四颗也是最后一颗卫星,最近成功完成了太阳能电池阵列的测试部署,以确保其在太空中正常运行。

这项关键测试证实,当 GOES-U 到达地球静止轨道时,卫星的大型五面板太阳能电池阵列(在卫星发射时折叠起来)将正确部署。在这次测试中,工程师们在模拟太空零重力环境的轨道上展开了五个面板。每个太阳能电池板高约 13 英尺,宽 4.5 英尺,重约 45 磅。

一旦 GOES-U 到达轨道,部署的太阳能电池板将形成一个单一的太阳能阵列机翼,每天旋转一次,以持续将其光伏(太阳能)电池指向太阳。光伏电池将太阳能转化为电能,为整个卫星供电,包括仪器、计算机、数据处理器、传感器和电信设备。太阳能电池阵列将为卫星产生超过 5,000 瓦的电力。这相当于您家中运行中央空调系统所需的功率。

太阳能电池阵列由洛克希德马丁公司在其位于加利福尼亚州桑尼维尔的工厂开发和建造,并在洛克希德马丁公司位于科罗拉多州利特尔顿的工厂进行测试,GOES-U 就是在那里组装的。GOES-U 计划于 2024 年 4 月发射。

GOES-R 计划是 NOAA 和 NASA 之间的合作项目。NASA 为 NOAA 建造和发射卫星,NOAA 运营这些卫星并将其数据分发给全球用户。这些卫星为天气预报和警报提供关键数据,检测和监测火灾、烟雾、雾、火山灰和灰尘等环境危害,并监测太阳活动和太空天气。
