THE HAPPY SATELLITE NERD EPISODE 87
In this video we do a Blind Scan with the #EdisonMio+ 4k #FTA #FreeSatelliteTV Receiver of G 16 and I explain how the coverage of satellite beams work.

How many geostationary satellites are needed for global coverage?
In theory, 2 satellites in diametrically opposite geo-symchronous orbits could cover the planet. In order for the satellites to communicate, a minimum of 3 would be needed, each at a 60 degree angle to the others. At this point, the strength and quality of coverage increases proportionally to the number of satellites.
What is a geostationary satellite used for?
Geostationary communication satellites are useful because of their large coverage, extending 81°, and stationary position in the sky, eliminating the need for movable ground antennas.
How far is a geostationary satellite from Earth?
35,786 km
A geostationary equatorial orbit (GEO) is a circular geosynchronous orbit in the plane of the Earth's equator with a radius of approximately 42,164 km (26,199 mi) (measured from the center of the Earth). A satellite in such an orbit is at an altitude of approximately 35,786 km (22,236 mi) above mean sea level.
Which goes faster a LEO satellite or a GEO satellite?
Unlike GEO satellites, LEO satellites also fly at a much faster pace because of their proximity to Earth. For example, an Iridium® satellite flies at approximately 17,000 mph (completing an orbit every 100 minutes!), compared to a GEO satellite that typically flies around 7,000 mph.
How many geostationary satellites are there?
According to Satellite Signals, there are 402 satellites in geosynchronous orbit. At geosynchronous orbit, the “ring” around Earth can accommodate a number of satellites - 1,800 altogether, according to one analysis by Lawrence Roberts, published in the Berkeley Technology Law Review.
On Galaxy 16 The Channels are Lesea Channels, This TV, Fox, NBC, Bvovn, NPR, GDMX, Living Faith TV, Cornerstone TV, HSN, The Light TV, and FETV
Is there still free satellite TV?
There is a free satellite TV solution for consumers who want a variety of television channels without paying ongoing subscription fees. Free to Air satellite television channels are unencrypted and legally available to the public for no charge.
Free-to-air (FTA) are television (TV) and radio services broadcast in clear (unencrypted) form, allowing any person with the appropriate receiving equipment to receive the signal and view or listen to the content without requiring a subscription, other ongoing cost or one-off fee (e.g. Pay-per-view). In the traditional sense, this is carried on terrestrial radio signals and received with an antenna.
FTA also refers to channels and broadcasters providing content for which no subscription is expected, even though they may be delivered to the viewer/listener by another carrier for which a subscription is required, e.g. cable, satellite or the Internet. These carriers may be mandated (or OPT) in some geographies to deliver FTA channels even if a premium subscription is not present (providing the necessary equipment is still available), especially where FTA channels are expected to be used for emergency broadcasts, similar to the 112 emergency service provided by mobile phone operators and manufacturers.
Free-to-view (FTV) is, generally, available without subscription but is digitally encoded and may be restricted geographically.
Free-to-air is often used for international broadcasting, making it something of a video equivalent to shortwave radio. Most FTA retailers list free to air channel guides and content available in North America for free to air use.
