<egg|anbo|egg> calculation which is plainly wrong, and should have been (3040 km * 7.5 km/s) (16 / (750 m)² + 5 / (375 m)²)
<egg|anbo|egg> at which point we are at one megapixel per second, on ~15 bit pixels, which is consistent with the data rates
<egg|anbo|egg> and they are scraping pixels off the edges of their scans when the next scan along the swath would overlap, so they are clearly data-rate limited, which I guess answers my question
<raptop> hm
<egg|anbo|egg> (and then obviously they pack in a sensor with a matching resolution, but fundamentally if they had the data rate it’s not like they couldn’t use a denser sensor/sampling rate)

<raptop> Well, DSN upgrade as a reason to launch new sats is now in the mission concepts

<egg|anbo|egg> I wonder if I can get away with not modeling sensor density & FoV
<egg|anbo|egg> fundamentally VIIRS is a 19,1 cm telescope with a fairly narrow FoV, and its massive effective FoV comes from being spun https://media.discordapp.net/attachments/433143814643777536/801593388264587274/unknown.png
<egg|anbo|egg> on a spacecraft with a fixed telescope you could spin the spacecraft to get an arbitrary FoV in one dimension (that’s how SEVIRI works)
