I believe it's a bit closer to 67%.

Density matters! Or is it matter makes density? If your dense does it matter? If you're not matter does that give you energy?

However, there could be a lot of difference in the bandwidth. Regardless of the sat-to-sat speed, the downlink/uplink will still be the gating factor. bp <part15sbs{at}gmail{dot}com> On 1/30/2020 11:40 AM, [email protected] wrote: <blockquote> In a vacuum it should be the same.

The early sats (the ones other than the first 60) do not have the laser communications between them, but they do have an RF link between them.

There is no inner satellite communication. Everything has to come down to ground stations right now.

That brings the functional constellation to 180 sats. The first batch of 60 don't count since they are not equipped to communicate with each other. Various reports say either 300 or 400 sats are required to get a basic minimal functioning system. At the rate they're going, this may mean they will have achieved their goal in another couple of months (they want to do 2 launches per month). https://www.space.com/spacex-starlink-3-satellites-launch-rocket-landing-success.html -- bp <part15sbs{at}gmail{dot}com> -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com </blockquote> -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com </blockquote> -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com </blockquote> -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com </blockquote> -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
