Article says orbit 715-790 miles and useful life 5-7 years, decay within 1 year after that.

Usable, low-maintenance LEO would probably start around 200 miles, but IANARS (I am not a rocket scientist). bp <part15sbs{at}gmail{dot}com> On 11/17/2016 11:36 AM, Adam Moffett wrote: ....yeah but GPS doesn't need an uplink. So if you have an antenna of similar size and shape to one of those cone shaped GPS antennas, how much tx power do you need to hit sats in LEO? That's at least a hundred miles up isn't it? ------ Original Message ------ From: "Mike Hammett" <af...@ics-il.net <mailto:af...@ics-il.net> > To: af@afmug.com <mailto:af@afmug.com> Sent: 11/17/2016 11:53:49 AM Subject: Re: [AFMUG] Space X, Satellite internet 1 GBPS, FCC They won't need to be south-facing.

Seems to me even with all those sats, talking about gigabit service to customers is a bit of marketing hype. Speaking of marketing, that would seem to be the key, how will they market this? Unless the target market is the same people who bought Iridium phones. SpaceX does not have a natural existing marketing vehicle for Internet service, I assume they will need partners or resellers. That is the advantage a Verizon, AT&T or DISH has – millions of existing customers they can advertise to, and offer bundle deals to. Satellite does have a natural appeal to the “nothing on my house” people, you can stick the antenna on a short pole in the yard. Still not a great solution for the apartment and condo dwellers without south facing balconies, they want indoor wireless modems. I am assuming the LEO orbits will still be in the southern sky like GPS sats, maybe that is wrong and they will whiz overhead in all directions?
