It's still at the "technical challenge to fuse data from AIS [ADSB for ships, complete with spoofing and transponders being turned off] to [generally] static images from multiple different sources" stage, at least unless you've got the budget for a video satellite to stick in a geostationary-ish orbit

I also wasn't sure how good satellite image quality is where you can match a ship from above, maybe the pattern of the freight containers could help.

And track I didn't indicate frequency, it's not per minute, but say hourly.
