How effective is an internet connection from a CubeSat?
I'm curious, I've read about radio comm and this article mentions using the GlobalSat or Iridium network is possible, but would that (or any other option) be a "broadband bandwith" available to whatever software is running on the CubeSat?
- tectonic 7y agoFor the radio & antenna you'll probably have on a small CubeSat, expect slow and unreliable, but it depends on if you're running your own ground station, in which case you may only be able to communicate for minutes a day or less, or are using a large ground station network or satellite constellation like Iridium, which will still be slow, but will offer much more frequent communication opportunities.

- lozaning 7y agoIDK what speed you should expect, but Amazon's ground station solution should at least increase availability: https://aws.amazon.com/ground-station/ https://aws.amazon.com/ground-station/
- Rebelgecko 7y agoIt's relatively easy (emphasis on relatively) to use a RF module similar to what you'd get for $20 on Sparkfun or Adafruit and get dial-up levels of performance without needing to invest in a crazy ground station. You'd be limited on when you can downlink. I would imagine that for higher bandwidth communications (like enough for realtime video) you'd need to worry about radio licensing.
