Satellite Technology Overview

- A good backgrounding in the basic technologies used in today's communications satellites. Presented by Mark Long, well known technology writer in the field of satellites. Covers C-band and Ku-band, large and small dishes, two-way dishes for broadband internet, and much more.
8:28 "A geostationary satellite, as you know, is essentially a mirror in the sky. It has transponders and communications come up to the satellite from the terminal, down to the network operations center where the routing and control logic takes place and all the customer care and back end billing system logic. Then it goes back up to the satellite and then off to one or more terminal sights."
I had two C-Band & KU-Band systems from 1992-2000. I tried to get another system in 2016 but the business had died! I found a couple of systems in 2016 but no one to install them. I miss those open feeds & raw live news reports.

Happy to discover your channel.
Very good ser thanks for this information
Thanks
Hi where can I purchased the DVD for home study?
GPS is ground based, just like Satellite. The Dishes communicate with each other via Aether.
Lol
What on earth are you talking about?
@@Testequip Flat earth.

"GPS is ground based just like satellite"
"flat earth"
Flat earth doesn't exist. We engineer certain technologies to overcome the obstacles of earth's curve
As a retired electronics engineer telecommunication (ICT) I engineered, commissioned, and maintained backbone telephony microwave radio systems, telephony satellites in the geosynchronous 36000km orbits (Hartebeeshoek Earth Satellite station South Africa) including the previous coaxial cable transmission systems both terrestrial and undersea and the latest next generation optic fibre transmission technology. Undersea optic fibre launch platform at Yzerfontein South Africa. Geosynchronous means it matches earth's rotation.
Satellites prior to around 1990 were the primary medium used by telecoms worldwide for their backbone network. Currently satellites are used for redundancy and other services such as VSAT for bank ATM's, point of sales, commercial TV etc. Don't confuse telephony backbone networks with satellite phones. It's not the same.
We have roughly 3 million radio amateurs (Hams) worldwide who have 20 of their own satellites built by Hams and master engineering students and used for making long distance communications.
Telephony satellites relay signals around a rotating and curved earth as radio waves travel in straight lines and line-of-sight has to be maintained.
Don't confuse satellites with "ground based" backbone cellular/GSM network radio systems, or point-to-point microwave radio systems, and/or systems connecting your mobile phone to the cellular network. It's not the same.
I'm not sure where you getting your information from, but your comment is incorrect. Earth is certainly not flat!
@@Testequip It's okay ding dong. Don't hurt ur big brain.
你好stud
