Re: AWS Ground Station

I recall looking at this a while ago, but I couldn't seem to find what kind of RF hardware amazon is using, is there any information on that?

Per the Details page:

"You can connect with any satellite in low Earth orbit (LEO) and medium Earth orbit (MEO) operating in X-band and S-band frequencies, including: S-band uplink and downlink, X-band narrowband and wideband downlink."

I thought this was an April fools joke once I clicked on the link. The bandwidth they are operation on (54 MHz) is ridiculous though! Truly sci-fi-ish stuff going on here. Also, did Amazon build this from scratch or did they acquire a company that had the basic infra for this kind of stuff?

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.

What’s unclear to me is, if any company can run their own satellite fleet, even micro ones, can they really not afford to run their own ground stations too? What’s the target customer profile of this service exactly?

I worked at a company that with a fleet of microsatellites that also built and managed our own network of groundstations. The costs of groundstations can definitely add up. Scouting for locations with good RF properties takes a lot of long flights, weird dealings with customs (RF equipment is questioned heavily). Then you have to find a site to host it, maybe ask them to beef up their security, construction to support your hardware once it gets above a certain size (dishes and radomes for S and X band comms), network connections and redundant network connections, and a team of people to manage and coordinate all of it. It's certainly its own undertaking and could easily be outsourced to a service with the right specs. Whether AWS's offering here will rise to meet that is yet to be seen.

It's the same argument as - if a company can run a multi-billion dollar operation, can they not afford their own datacenters? They can, but AWS just makes things easier and often cheaper.

The core competency of a business you describe is building, launching and maintaining satellites. On-ground network infrastructure, computing hardware, data processing, machine learning etc. is something AWS is a lot more familiar with.

I wonder if this is related to Amazons Project Kuiper satellite broadband constellation, would make sense for them to be building out their ground station capabilities.

Probably more likely an offshoot or requirement from Blue Origin.

Could this be used for downlink only? For example, to pull down NOAA satellite data?

I'm like 90% sure it would be cheaper to just build your own antenna and an RTL-SDR setup to do that sort of thing yourself. There's no way it's cost effective for that.

I would say "it depends", when it comes to cost. You can build your own grown station for UHF/VHF bands at under $1000.

S-band and beyond will cost you more, but a fully-featured VHF/UHF/S-band one from a proper vendor will be under $100K.

X-band, yeah... But not that many cubesats have X-band transceivers anyway.

More likely Kuiper.

This is the classic "make or buy" decision. You can rent by the minute, or own your own.

What the Amazon website doesn't cover is:

- download guarantee. They rent you the antenna, they don't commit to a successful reception (and consequent refund if it fails)

- link status report (needed for a positive confirmation of successful reception.) This is basically a series of SNR measurements

- competition with other users of the same antenna: first-come first served? Maybe your spacecraft needs more storage to save the downlink data if the Amazon antenna is busy.

And of course they don't talk about the competition.

Yes, I agree. Comes with probably the same caveats as all other Amazon services.
