Velocity Of Satellite In Orbit

Thanks to physics if you know the mass and altitude of a satellite in orbit around the earth you can calculate how quickly it needs to travel to maintain that orbit.

Velocity of satellite in orbit. In space gravity supplies the centripetal force that causes satellites like the moon to orbit larger bodies like the earth. Its velocity the speed it takes to travel in a straight line and the gravitational pull that earth has on it. Calculates the orbital radius and period and flight velocity from the orbital altitude. Delta v more known as change in velocity symbolized as v and pronounced delta vee as used in spacecraft flight dynamics is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon or an in space orbital maneuver it is a scalar that has the units of speed as used in this context it is not the same.

R 3 897 x 10 7 m the orbital radius for this satellite is 3 897 x 10 7 m. This change will push the satellite into a lower orbit which will increase its forward velocity. The orbital velocity of the international space station is 7672 m s. Where g is 6 673 x 10 11 n m 2 kg 2 m central is the mass of the central body about which the satellite orbits and r is the radius of orbit for the satellite.

Taking the square root of each side leaves the following equation for the velocity of a satellite moving about a central body in circular motion. A satellite orbiting closer to the earth requires more velocity to resist the stronger gravitational pull. Orbit of a satellite calculator high accuracy calculation welcome guest. Orbital velocity is the velocity needed to achieve balance between gravity s pull on the satellite and the inertia of the satellite s motion the satellite s.

Its velocity the speed it takes to travel in a straight line and the gravitational pull that earth has on it. With satellites the object is not to escape earth s gravity but to balance it. A satellite maintains its orbit by balancing two factors. The orbital radius can be found by rearranging the orbital velocity formula.

Eccentricity refers to the shape of the orbit. A satellite with a low eccentricity orbit moves in a near circle around the earth. In gravitationally bound systems the orbital speed of an astronomical body or object e g. Planet moon artificial satellite spacecraft or star is the speed at which it orbits around either the barycenter or if one object is much more massive than the other bodies in the system its speed relative to the center of mass of the most massive body.

Earth s escape velocity is much greater than what s required to place an earth satellite in orbit. In addition to height eccentricity and inclination also shape a satellite s orbit. A satellite maintains its orbit by balancing two factors. What is the orbital radius.
