Well the US Navy proved they can enforce the parking rules back in 2008. To quote Sheldon Cooper, “You’re in my spot”

There is only one orbit height that rotates around the earth at the same speed as the Earth rotates and it is located at the equator. That is called the Clarke Belt and it is 22,236 miles above the earth. Your question about a Leo and it being Geostationary are contradictions in terms. In the Clarke belt since it’s just one line of “parking spots” around the earth (at the equator only), one does not just set up their own. They are very coveted spots in the belt and only the expensive birds reside there. At 22,236 miles above the earth, a Cambium radio or similar device won’t have enough power to reach back to a CPE. In addition to that and you will have high latency just like the current geostationary satellite systems do. That radio signal has to travel 44,472 miles, hence the latency people complain about. https://en.wikipedia.org/wiki/Geostationary_orbit Thank you, Brian Webster www.wirelessmapping.com <http://www.wirelessmapping.com/> From: AF [mailto:af-boun...@af.afmug.com] On Behalf Of Robert Sent: Thursday, February 25, 2021 4:31 PM To: af@af.afmug.com Subject: Re: [AFMUG] Your Own Satellite Internet Yes, Look up the various "xxxxStats" that have been tethered at the borders over the years with balloons for radar coverage of low flying aircraft and the NOTAMS that are posted for them. They have a very large ( relatively ) exclusion zone and you have to worry about said tethers falling and doing damage on the way down.

Many times any of the Amateur radio satellites only have a 10 or 15 minute window of visibility a few times a day. For 24/7 internet service you need to have many orbital object/satellites such that when one move out of view another is there for the handoff. The lower orbit you have, the smaller window you have. So a LEO small footprint coverage is still going to take a lot of satellites just to cover you small territory. How many all depends on the area and altitude. Since your satellite is not going to be in a stationary orbit, I am sure you need international cooperation to file for all the orbits you need to just cover your small footprint in the US because that orbit goes all the way around the earth and has effect on others who might need a similar orbit. A good portion of the time your satellite is flying through the sky for your local footprint, it’s not going to be doing much of anything because it’s not visible to any of your customers. Until we get some sort of tethered satellite solution that is tied to the ground and centrifugal force hold the satellite in place, these are the laws of physics one has to contend with. If someone can invest a very lightweight tethering string of some sort that when it is long enough the total weight of said string does not overcome the amount of centrifugal force achieved at your desired height to allow the radio/satellite to stay in place without needing to be an orbital object. If that is invested and it also allows for transmission of adequate power and data, that could be a real game changer. As far as I know 90,000 feet of something to be a good tether weighs more than the force that could keep the device flung out that far. Error! Filename not specified.

It needs a lot of speed. That speed would have it moving "past" you really really fast until you got to about 26k miles up where it would remain still relative to you. If you wanted it to float at 90k' you would need a balloon or something like that but that's a loony idea.

I've been to low earth orbit (90,000 feet) with equipment I can get in my basement/hardware store. I've beamed signals back from 90,000 feet to a radio in my truck. I'm familiar with how AmSats work (although have not sent one up myself). What is preventing a WISP from putting together a solar powered GeoSync satellite that has a few Cambium Spots on it to fully cover your coverage area? Yes, you'd have capacity issues if you didn't plan it correctly, but is there technically any reason I can't run a 5GHz link to a satellite? Do you have to pay a "rental" fee to occupy a space in space to park your bird? Yes, I realize there would be latency, but if you keep the throughput there (something Hughes Doesn't Do), the experience wouldn't be half bad for most things.. -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 <https://www.google.com/maps/search/401+E+Pratt+St,+Ste+2553+Baltimore,+MD+21202?entry=gmail&source=g> Baltimore, MD 21202 <https://www.google.com/maps/search/401+E+Pratt+St,+Ste+2553+Baltimore,+MD+21202?entry=gmail&source=g> (410) 637-3707 -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com <image001.gif><image002.jpg><image002.jpg>-- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
