Lou Schneider Posted May 29, 2019 Report Share Posted May 29, 2019 (edited) How many "thousands of satellites" LEO systems can we deploy before they start posing a threat to space launches that have to pass through their orbits? Most of the present space junk is in an equitorial orbit, close to the geosynchronous arc which occupies a small percentage of the available sky. The LEO constellations are lower orbits, so their web will be everywhere and constantly in motion across the sky. Better and faster Internet access is fine, but I'd hate to see space launches constrained or placed in danger from having to pass through the paths of these constellations.

Carlos Posted May 29, 2019 Report Share Posted May 29, 2019 They don’t cause any issues. This is part of the planning and testing. It’s impossible not to make these puns, but the space in LEO is...astronomical. Quote Link to comment Share on other sites More sharing options...
Sehc Posted May 29, 2019 Report Share Posted May 29, 2019 Earth orbit is not astronomical. Cluttered orbits, space junk, is already a problem. What happens when other countries appropriate as many satellite orbits as the USA? Quote Link to comment Share on other sites More sharing options...

(image) Yes, Elon has mentioned the "pizza box" antenna/receiver a number of times. It will be interesting to see how adaptable it is to portable RV use rather than just RV roof use. It won't need aiming, but it will need a clear sky view.

Carlos Posted May 30, 2019 Report Share Posted May 30, 2019 Yes, it's important to remember that this is still satellite, and still not as "portable" or as easy to use as cellular. The current satellite systems such as BGAN use an antenna like this, which likely will still be used with the new stuff, at least at first: Quote The big differences in the new system are the orbit level, and the throughput. Current systems orbit higher, which means farther, which means high latency. Latency makes some applications annoying and others unusable. Web usage with high latency means an annoyingly slow response to clicks. For things like voice and two-way video, it means a long delay between the person speaking and the person hearing. I have had two satellite phones, and had to train everyone I talked to that they need to wait half a second between speaking and hearing a response. The throughput on this is huge, while old systems were super slow. That means the old systems had to charge a lot. These will have lots of capacity so it will be cheap.

(price per bit). and who here thinks we need more trash in orbit around this small blue marble? with in 20 years there will be a couple major crashes up there. and make billions of more junk things flying around at 10 of thousands of mph. in 30 years at least one human will die thanks to all the junk up there. https://en.wikipedia.org/wiki/Space_debr http://go.discovery.com/dscovrd/space/this-is-how-much-garbage-weve-left-in-orbit-around-earth/ Quote Link to comment Share on other sites More sharing options...
