What is the space orbital?
A space orbital refers to the path that an object, such as a satellite or a planet, follows as it moves around a celestial body due to gravitational forces. It is characterized by its shape, size, and orientation, which can be circular, elliptical, parabolic, or hyperbolic. The specific parameters of an orbital, including its altitude and inclination, determine the object's behavior and function in space exploration or communication. Understanding orbital mechanics is essential for satellite deployment, space missions, and planetary motion.
What can you infer about the linear velocity of a satellite in an elliptical orbit as it travels from perigee to apogee?
The linear velocity of a satellite in an elliptical orbit increases as it moves from perigee (closest point to Earth) to apogee (farthest point from Earth) because the gravitational pull is weaker at apogee, causing the satellite to speed up. At perigee, the satellite moves faster due to the stronger gravitational pull from Earth.
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.
What do you mean by elliptical trajectory?
Any planet that orbits a star ( our sun for example ) has an orbital trajectory. This is due to gravity and the centripetal force. An elliptical trajectory is when that planet orbits the star in an ellipse rather than a circle. Ellipse = squashed circle.
What are the four orbit levels for satellite systems?
LEO (Low-Earth-Orbit)-100 to 1000 miles out • Used for wireless e-mail, special mobile telephones, pagers, spying, videoconferencing MEO (Middle-Earth-Orbit)-1000 to 22,300 miles • Used for GPS (global positioning systems) and government GEO (Geosynchronous-Earth-Orbit)-22,300 miles • Always over the same position on earth (and always over the equator) • Used for weather, television, government operations HEO (Highly Elliptical Earth orbit)-satellite follows an elliptical orbit • Used by the military for spying and by scientific organizations for photographing celestial bodies

What type of antenna is used for satellite communication?
parabolic
What are some real life examples that apply conics?
> Heaters, satellite dishes, parabolic lights, motion of the planets, telescopes, eyeglasses, shadows on a wall, a ton of sh*t basically Satellite dishes and the mirrors in reflecting telescopes are both parabolic in shape. The stream of water from a drinking fountain travels a parabolic path. The orbit of the moon around the earth and the earth around the sun are elliptical. I'll bet you can find some real-life examples of circles on your own.
What is an elliptical satellite?
An elliptical satellite is a type of satellite that orbits Earth in an elliptical path, meaning its distance from Earth varies throughout its orbit. This results in the satellite moving closer to and farther from Earth as it completes its orbit. Elliptical satellites are commonly used for applications like communication and remote sensing.
Is there a difference between a parabolic reflector and a parabolic dish?
A parabolic reflector typically refers to a curved surface that reflects or focuses light, sound, or radio waves to a specific point. A parabolic dish specifically refers to a type of parabolic reflector commonly used to collect or reflect electromagnetic waves, such as in satellite dishes. While they are both parabolic in shape, a parabolic dish is a specialized form of a parabolic reflector designed for a specific purpose.
What uses are there for parabolic mirrors?
Parabolic mirrors are formed in a dish like shape, the purpose of it's shape is to transmit the electromagnet waves. For example when using a microwave or watching a television, it is through electromagnet radiation that make it possible to function. Television receives the signals via the satellite dish, the satellite dish acts as the parabolic mirror.
What shape is the mirror used to reflect TV waves from a satellite?
Probably parabolic (not 100% on that thou)
If a satellite's radial velocity is zero at all times its orbit must be elliptical or parabolic?
Not necessarily. A circular orbit around a central body, such as a planet, would also have a radial velocity of zero at all times. In a circular orbit, the satellite's velocity vector is always perpendicular to the radius vector, resulting in a constant radial velocity of zero.
A satellite in an elliptical orbit gains speed when it?
A satellite in an elliptical orbit gains speed when it moves closer to the body it is orbiting due to the conservation of angular momentum. This increase in speed occurs as the gravitational force from the body pulls the satellite inwards, causing it to accelerate.
Where is the primary body in the elliptical orbit of the maverick weather satellite?
The primary body, earth, is at the foci point closest to the pedigree. At the pedigree the radius is shorter than it is at the apogee.
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 is a statelite?
Satellite Dish is a dish-shaped type of parabolic antenna designed to receive microwaves from communications satellites, which transmit data transmissions or broadcasts, such as satellite television.
