A home to friendly weirdos. The Grey Gardens of the Fediverse (but beige). Occasionally graphically cacographic. Definitely probably not a cult (though you'll never be 100% sure). Beige-bless 🙏

Anyone out there know about satellite internet tech? How many geostationary satellites would it take to provide a wireless net connection to every net-enabled device in Aotearoa?

Is a satellite a realistic thing for a forward-looking government to pay for, to guarantee sovereign intra-government communications? Plus emergency comms during natural disasters.

@strypey This doesn't exactly answer the question, but it comes close and should give you what you need to determine details.

AnswersWhat is the minimum number of satellites needed to cover the whole Earth? - AnswersThe absolute minimum number is for momentary complete cover is 4 in a triangular prism shape, but these will not stay in the right positions as they are not in a geostationary orbit. 3 in geostationary orbit will give very bad and failing coverage at the poles and at the outer edge of their footprint 6, 3 in polar orbit and 3 in geostationary orbit will help, but for a practical coverage 4 in geostationary orbit and 4 in polar orbit will be more practical

I can see two answers, which directly contradict each other, and offer no references. Thanks anyway, but answers.com seems more like noise than signal to me.

@strypey Sorry...boosted for reach. I'm not a rocketry or satellite guy so I can't give you a better answer...just bits and pieces picked up over the years.

GPS seems to take 31 satellites, according to BBC.
