Sorry, but what would be the use case for running code on a satellite?

A few solid cases are: - space-qualification for the satellite control software. You need to test your own flight software in space, so you use our satellite platform to run test/validation and then reuse on your own satellite. - space-based algorithm tests, such as data compression/error correction or radiation hardening through software means. Inter-satellite link protocols is also a rich field for software develop…

This was sufficiently close in timing that I wasn't sure for a moment whether this was just an early caught April Fools. Then again, the more I think about it, the more this makes sense. Satellite business is hard and capital intensive enough as it is, for starters in the micro-satellite business it would be absolutely prohibitive to run their own hardware just to receive those signals.

They do have some impressive "I didn't know anyone would need that!" services. I also love this one: https://aws.amazon.com/snowmobile/ > AWS Snowmobile is an Exabyte-scale data transfer service used to move extremely large amounts of data to AWS. You can transfer up to 100PB per Snowmobile, a 45-foot long ruggedized shipping container, pulled by a semi-trailer truck. (...)

What's so weird about 54mhz? It's very close to the somewhat commonly used 6 meter band by hams

Bandwidth and frequency are very different. They have a 54MHz wide uplink, at whichever of the supported bands you want.

I work on Google Cloud and have an obvious bias here, but having thought about this for a couple year now, this does not seem like a good or cost-effective way to move that much data. In particular if you have ~100PB of data to move and you are in a location that can be reached by a 45-foot long shipping container on a truck with access to the ~350KW of power it takes to run Snowmobile, you're clearly not somewhere _…
