There are essentially three types of Earth orbits: high Earth orbit, medium Earth orbit, and low Earth orbit. Many weather and some communications satellites tend to have a high Earth orbit, farthest away from the surface. Satellites that orbit in a medium (mid) Earth orbit include navigation and specialty … Meer weergeven Just as different seats in a theater provide different perspectives on a performance, different Earth orbits give satellites varying perspectives, … Meer weergeven Together, the satellites height, eccentricity, and inclination determine the satellites path and what view it will have of Earth. Meer weergeven Changing a satellites height will also change its orbital speed. This introduces a strange paradox. If a satellite operator wants to increase the satellites orbital speed, he cant simply fire the thrusters to accelerate the … Meer weergeven A geostationary orbit is extremely valuable for weather monitoring because satellites in this orbit provide a constant view of the same surface area.
