I think there’s going to be an API for everything renissance and this is just another example. As a coder being able to automate all the things and create new businesses, processes, workflows it’s a great time to be a coder. Aka reaching beyond the cloud.

Did you mean "there’s going to be an API for everything reconnaissance"?

Probably renaissance

Seems somewhat similar to what Descartes Labs is doing - a "data refinery that combines data from diverse sources, cleans it up and makes it ready for modeling - and a platform to upon which to build living, learning models" [1]

Some might be encrypted, but I don't think they are all encrypted: https://www.rtl-sdr.com/rtl-sdr-tutorial-receiving-noaa-weat... Usually the export laws and restrictions (ITAR) refer to the technology used to launch the satellites, not the data they downlink. But if you had the key, you could also use encrypted satellite data. (Edit note: the parent changed their text to say intelligence data, which is obviously no…

Pretty sure NOAA also regulates the use and encryption of the data collected. Also the keys are typically in an HSM with lots of security protocol and air gap, so good luck with that.

NOAA scans the earth like a big scanner and sends the data down for anyone to pick up and get an image of the globe. It's not encrypted.

Another amateur radio sidenote for the day[0], SATNOGS[1] performs a similar task by tracking and recording satellite passes of LEO cubesats with amateur radio telemetry and communication payloads via a network of DIY ground stations. Anyone can see a history of any pass of a tracked satellite over a particular station including a RF spectrum waterfall, audio capture, and telemetry output if supported.

The SATNOGS receivers, usually a low-cost RTLSDR, cover a much wider spectrum than just amateur bands (which prohibits commercial use of it's spectrum), so I wouldn't be surprised if non-amateur entities are eyeing the service, or if SATNOGS organization is thinking about going commerical (although there's already competition in this field besides AWS Ground Station).

Of intelligence data there is. Read up on ITAR and EAR. So you don’t think that the satellites AWS will interface with will be facing earth with sensors?

I’ve worked in an ITAR industry. This topic isn’t about intelligence data :)

Agree, I also worked under ITAR restrictions in the launch industry.

There is a fairly narrow cone you would need to be in to intercept the data but if its intelligence related then it’s definitely encrypted thanks to export laws. ITAR and EAR https://www.bis.doc.gov/index.php/policy-guidance/encryption

There are no “export laws” requiring encryption of satellite transmission data. Export laws wouldn’t apply anyway. As a constructive counter example, there are plenty of free services you can tune into.

NASA telescopes used to be governed by ITAR. They've relaxed those a lot, but you had to use software to transmit the data encrypted all the way to your science pipelines (e.g. Telescope to White Sands to Goddard to $INSTITUTION)

Looks very interesting. Looks like they use the NORAD ID to get frequency information for the various channels? I wonder what frequencies/bands they will support (since this gets down to the RF hardware on the groundstations)?

Since they're asking for FCC license info and there isn't a canonical Norad ID to frequency source, I assume the Norad info is just for tracking, Doppler, and scheduling of passes.
