Assuming at least 40KM distance from the earth, (40/300) * 2 means a roundtrip time of 267ms. That's without processing time, but that's probably in the ballpark of <5 ms.
This excludes many types of internet use cases.
- dasmoth 11y agoI assume you mean 40,000 kilometres here. That'll definitely be lower than that (at that kind of height, you wouldn't need hundreds of satellites for global coverage). Wiki page talks about 800km and 950km orbits.
- andor 11y ago800km is not so far, it's much closer than Europe to North America, US East Coast to West Coast, etc. A round-trip at speed of light should take about 5.3ms.
- lmm 11y agoThe speed of light is 300 Mm/s, not 300 Km/s.
