Velocity Of Satellite In Elliptical Orbit

The earth has an absolute surface value of g of 9 821 m s and has a radius of 6371 km.

Velocity of satellite in elliptical orbit.

Tangential velocity components for the correct case of elliptical orbits. Its maximum and minimum velocities of satellites are 3 1 0 4 m s and 1 1 0 3 m s respectively. And the remaining three satellite orbits are of elliptical corresponding to the eccentricity e values 0 5 0 75 and 0 9. As the force is central angular momentum is conserved.

The satellite s initial position and velocity vectors and at a given epoch. Begingroup photon at positions a and b the velocity of the satellite is at right angles to the straight line joining the centre of the earth to the satellite. R a 1 e2 1 ecos 1 the velocity of an object in polar coordinates is v v rrˆ v ˆ 2 r rˆ r ˆ 3 differentiating 1 we get r dr d 4 ae 1 e2 sin 1 ecos 2 5. An orbit equation defines the path of an orbiting body around central body relative to without specifying position as a function of time if the eccentricity is less than 1 then the equation of motion describes an elliptical orbit.

2 126 an earth satellite which moves in the elliptical equatorial orbit shown has a velocity v in space of 17 970 km h when it passes the end of the semi minor axis at a. A satellite moves in elliptical orbit about a planet. A satellite in a low orbit or low part of an elliptical orbit moves more quickly with respect to the surface of the planet than a satellite in a higher orbit or a high part of an elliptical orbit due to the stronger gravitational attraction closer to the planet.

For a satellite the point which is closest from the earth is known as perigee. In above figure the satellite orbit corresponding to eccentricity e value of zero is a circular orbit. From initial position and velocity. Because kepler s equation has no general closed form solution for the eccentric anomaly e in terms of the mean.

Determine the radius of curvature p of the orbit at a. We can start with the polar equation of an ellipse. When the satellite is in the part of its orbit closest to the earth it moves faster because the earth s gravitational pull is stronger.
