Advantages; they always appear to be in the same spot in the sky, so you can focus your satellite dish antenna on them.
Disadvantages; they are quite high, about 23,000 miles up. You need a fairly strong signal to hit them, and a handheld device often doesn't have enough power.
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
Yes that is the primary disadvantage of visible satellite imagery.
A Geosynchronous or Geostationary satellite. The orbit period of a satellite will be longer the further it is away from the planet, so these have to be quite far away to match the rotation period of the earth. They orbit the earth once every 24 hours, so stay in the same apparent position when 'seen' from earth. This means that satellite dishes receiving signals from it can remain still, pointing in one direction rather than having to track it across the sky - a big advantage.
GPS satellites orbit at 11,000 nautical miles above the Earth
Something that orbits a planet is a satellite.

A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
1963 by using a geosynchronous communication satellite called the Syncom Watch satellilte tv with satellite tv tuner like TBS TV Tuners
An example of a sentence using geosynchronous is "The geosynchronous satellite never moved in the sky."

Regarding the communications satellite orbit; a geosynchronous orbit is one that keeps the satellite in one position in the sky. It is a spot in space about 22,000 miles away that the satellite will orbit the earth once a day, so it is moving the same speed as the earth rotates and appears to never move. If your dish network satellite was not in geosynchrous orbit, you would need a device to turn your dish and there would be periods that the satellite would be over a different part of the world, like the sun and moon. They would slip over the horizon and you wouldn't be able to watch TV for a while.
YES As height increases, speed of satellite decreases.
That is called a geosynchronous orbit.
