简介
EUMETSAT发布MTG-I2卫星首批图像，FCI仪器从3.6万公里高空实现欧洲每2.5分钟高分辨率成像。对AI工程师而言，这种高频地球观测数据流是训练实时天气预测模型的稀缺燃料，遥感+时序预测的交叉领域正在出现新机会。
编辑判断
气象卫星数据历来是NASA和NOAA主导，欧洲这次把成像频率压到2.5分钟级别，直接对标GOES-R的15分钟全圆盘扫描，在强对流预警场景有代差优势。
对AI团队来说，真正的机会不在卫星本身，而在数据下游：EUMETSAT的数据政策比美国更开放，MTG数据通过EUMETCast免费分发，这意味着初创公司可以零成本获取亚分钟级的大气观测流。
做农业保险、可再生能源功率预测、或航空路径优化的团队，现在可以开始搭建基于实时卫星输入的预测管线，而不必再依赖延迟数小时的公开数据集。

核心争论：高频卫星数据对AI气象预测的价值与业余无线电爱好者接收卫星图像的可行性
I wonder how hard it'll be to capture some of these images yourself. NOAA decommissioned it's last LRPT/APT capable satillites. Russia has a couple open access 137MHz sats available Meteor M2-3 and M2-4 I believe they have become flakey with age, damage and other issues. Those you could stand i
It seems like someone did just that recently! They used an SDRplay rather than a cheap RTL-SDR but the antenna is simple. https://gdamdam.github.io/meteor-satellite-reception/meteor-...
That's a really nice write up and the SDR looks quite nice for the price. It brings back memories one of the things that made radio waves feel "real" to me was a similar setup where we raised and lowered the antenna parallel to the ground and saw the reflections strengthen the received signal or mak
