It won't because these are geostationary satellites (if I read the post correctly). So you'd need at least 3 of these to get a good image and that's not even considering some of the bigger issues with this. I also don't think the resolution is on par. But the images will be really cool to see.

- branchan 11y agoUhhh, this spacecraft is for a totally different application. Planet Labs doves are in LEO for low earth observation. This Japanese one is a weather satellite to monitor the area around Japan.
- bargl 11y agoYup that's what I was getting at, my first thought was that they'd be competing then I looked at the use cases and I wanted to point out that they were different, but I might have been the only one who thought that in the first place :-)
- callesgg 11y agothe resolution difference is quite big. Planet labs satellites captures with something like 1mx1m resolution. This satellite has a resolution of about 500mx500m
- blackguardx 11y agoI think it is actually 5m. 1m gets pretty close to spy satellite territory. The planet labs lens only has a focal length of <30cm.
- callesgg 11y agohttps://en.wikipedia.org/wiki/Planet_Labs https://en.wikipedia.org/wiki/Planet_Labs Yeah 3-5 meters apparently. And i would assume spy satellites can do much better than 1m. According to wikipedia spy satellites has a estimated resolution of about 10 cm.
- blackguardx 11y agoModern Spy Satellites certainly do. However, there are rules that govern what a non-governmental entity can put into space.
