Does dbs also known as direct broadcast satellite such as directv and dishtv orbit in a geosynchronous orbit?
Yes, the satellites orbit in a geosynchronous orbit, as with most all communications satellites. (Some exceptions are satellites such as the global positioning satellites.)

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.
Most rotate east to west - the same direction as the Earth below. This is a requirement for geostationary orbit, and requires the least energy for launch. But there are ot…her sattelites that travel in any other conceivable direction; the most common "weird" direction is pole to pole.
here's an unvetted list as per 10/2010 approx 450 Geo-sync orbits are hard to maintain as the orbit decays almost immediately upon achieving it, lending to low service lif…e span thus the list changes a lot positions are usually chosen on the 1/10 of a degree of the planets circumference so 360 x 10 is the ideal maximum amount of sats in this orbit at one time. there are slightly off orbits named super and sub geosynchronous which move slowly across the orbit either westerly or easterly, usually marked for junk satellites or discards, some electronic lab platforms have been put here however, the diameter of these orbits very and are often highly elliptical so pin pointing these related orbits and how many positions they offer is unlikely to be meaningful
YES As height increases, speed of satellite decreases.
Does dbs also known as direct broadcast satellite such as directv and dishtv orbit in a geosynchronous orbit and why?
YES Satellites in geostationary orbit have an orbital period that is exactly the same as the Earth's rotational period. This means that looking from Earth the satellite appear…s to be stationary in the sky. This means that satellite dishes can be fixed (or static) and do not require complex motorised mounts to follow the satellite across the sky. Also it means that the satellite does not rise or set and so is never hidden from view below the horizon.
Answer:. The term synchronous is defined as happening, existing, or arising at precisely the same time.. A geosynchronous satellite; therefore, stays in a fixed position rel…ative to the earth and as such, follows the rotation of the earth. Put another way, a geosynchronous satellite doesn't rotate around the earth; it simply keeps up with the rotation of the earth.
In geosynchronous orbit, it's always somewhere over the same meridian of longitude. In geostationary orbit, it's always over the same point on the equator.
If a satellite is in geosynchronous orbit, it will take the satellite 24 hours , a day, to orbit the Earth once. This is so because geosynchronous orbit is when a satellite o…rbit the Earth at such a time, that is is over the Earth at all times.
From Wikipedia: "All geosynchronous orbits have a semi-major axis of 42,164 km..." This is, in a way, the average distance from Earth's center. The distance from sea level wou…ld be 35,786 km.
No. To remain in orbit it needs to have a certain speed, and that speed will only match the surface speed of the earth on a certain height. To go lower it'd have to go slower,… and then it'd fall.
Satellites in geosynchronous orbit stay above the same point on earth's surface at all times. This means that the period of the satellite in its orbit of the earth is exactly …the same as the period of the earth's rotation. _____________________________________ Geosynchronous; geo = Earth, syn = equal, and Chronos was the Greek titan in charge of time. So geosynchronous means " equal time with Earth"; the satellite orbits the Earth in the same amount of time that the Earth spins. So a geosynchronous orbit is one in which the satellite takes exactly the same amount of time as the Earth to turn, and the satellite seems to hang suspended in space. This means that a satellite dish pointed at the satellite doesn't need to track the satellite, which does not seem to move.
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 mil…es up. You need a fairly strong signal to hit them, and a handheld device often doesn't have enough power.
All satellites follow an elliptical orbit - they are darn close to circular, but even a circle is an ellipse.
"Geosynchronous" only means it circles the Earth every 24 hours, but if it's not also in an equatorial orbit, then it would appear to bob up and down, north and south in t…he sky, every day. I think you're really asking about "geostationary" orbit, which, in addition to having a 24-hour period, is also over the equator, and appears motionless in the sky. The advantage is that anyone on the ground in the appropriate continent with a satellite dish can mount the dish on a little tripod on their garage, and receive signal from that satellite any time, 24/7/365. They don't need complicated and expensive machinery to track the satellite and constantly move the dish to keep it pointed at the bird. Also, if the satellite moves in the sky, then for any individual person you choose, that satellite will be down, set, not in his sky, for large portions of the time, and the satellite is of no use to him. If you place your satellite in an orbit that's not geosynchronous and geostationary, then you should expect not too many paying customers to sign up for your movie service.
