How do you transfer a satellite revolving around the earth in elliptical orbit into a circular orbit by retaining the apogee of the ellipse as radius of the circular orbit?

This very maneuver is performed by the Shuttle during every mission.
At launch, the Shuttle is on the ground, and then rises, and tilts to the east. The purpose of this particular path is twofold; first and foremost, to get above the vast majority of the atmosphere as quickly as possible, and second, to accelerate to something close to orbital speed. At the typical altitude that the Shuttle flies, this is about 18,000 miles per hour.
The engines can't run continually; they don't carry enough fuel. So they accelerate and then coast, on a ballistic trajectory that will bring them to just touch the altitude of the ISS. Then, just as they reach that altitude, they fire the main engines again to "circularize" the orbit.

Is a asteroid's orbit elliptical?
Yes. They orbit the Sun and as per Kepler's first law they follow an elliptical path. Do note that a circular orbit is a special type of elliptical orbit.
The potential energy of a satellite in an elliptical orbit is?
The total energy of a satellite doesn't change. At its closest approach to the planet, it has the most kinetic energy and the least potential, whereas at its furthest retreat from the planet, it has the least kinetic energy and the most potential. But their sum ... the satellite's total mechanical energy ... is always the same. (It may gain heat energy when the sun is shining directly on it, and lose it when it's in the planet's cold shadow, but neither of those changes affects its orbit.)
Is Earth's orbit's circular or elliptical?
It is slightly elliptical. It is farthest from the sun in winter and in summer and closest in spring and autumn. The seasons are determined as a result of the tilt of the Earth's axis and not the relative distance from the sun.
How do you define an orbit in astronomy?
An orbit is the circular or elliptical motion of one smaller body around another larger body due to gravitational attraction.
In satellite beams what is the difference between FSS and BSS?
BSS = Broadcasting Satellite Service (12.2->12.7Ghz) -- Usually for home reception. Uses circular polarization.FSS = Fixed Satellite Service (11.7->12.2Ghz) -- Usually for commercial reception. Uses linear (horizontal/vertical) polarization.
What is a satellite orbit?
A satellite's orbit is just the path it follows around the Earth or some other planet.Satellites' orbits can be elliptical or circular.
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
circular.
Does earth's gravity do any work on satellite revolving around it?
NO. The gravity of Earth, in conjunction with the inertia of the satellite, keeps the satellite revolving around Earth. However, the satellite doesn't get any nearer to the Earth. So, according to the laws of physics, no work is done. (I'm ignoring the fact that satellites sometimes lose height and need to be "boosted" a bit to maintain their orbits. Also, I'm assuming that the satellite's orbit is circular. If the orbit is elliptical the answer is more or less the same, but a bit more complicated.)
Why do Satellites travel in a circular path?
Satellites orbit the Earth or other bodies due to a careful balance of their velocity and the gravitational attraction of the body. Essentially gravity pulls them down but their velocity moves then out (Newton's Fist Law of Motion) at the same rate. They keep missing the body they orbit.The path is not necessarily circular since the gravity over the Earth varies with the density of the ground below the satellite. They are also satisfied to be in an elliptical orbit (closer at some times than others). The moon is a good example of a satellite in an almost circular elliptical orbit. comets have wildly elliptical orbits.
A satellite in an elliptical orbit travels at constant what?
If the path is perfectly circular, yes, the speed is constant. This should not be confused with the velocity, because while speed is constant, its direction is not; therefore velocity is always changing.
What will be the velocity of a satellite which is revolving around the earth in a circular orbit the radius R if the radius is increased from R to RR what will be the velocity?
the velocity will be velocity divided by square root of 2
Does a cone have a circular or elliptical base?
A cone has a flat circular base
Does the moon have a circular or elliptical orbit around the earth?
ALL orbits are elliptical.
Is the satellite accelerating?
Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.
Among elliptical orbits are some more circular than others?
Yes some elliptical orbits are more circular than others
What is an example of concentric motion?
Example: Moon revolving around the sun (although it's technically elliptical not perfectly circular) -speed is constant but velocity changes constantly since the vector changes direction but not magnitude.
What is the spinning force called?
Generally, rotation is the term for motion in a circular manner around a fixed line (the axis).Although the term "revolution" also refers to cyclic motion, it often refers to motion around an object or other fixed point. In astronomy, revolving is used for either circular or elliptical motion of satellites, while rotating refers to the spinning of a satellite such as a planet or moon.
