User: Satellites in low orbits require less or more velocity than higher orbits

User: Weather satellites are usually placed in North-South orbits because: They require a stationary transmitter. They focus on specific latitudes. They will eventually cover the entire globe. They are easier to maintain and manage from earth

Weegy: To achieve a syn-synchronous orbit, the orbital plane is inclined slightly away from a true north-south track to introduce a slow precession in the orbital plane, roughly one degree per day. [ This precession ensures that the equatorial crossing times of the satellites, in terms of the local solar time, remain nearly constant throughout the year. This means that a satellite can make repeated global observations from a single set of sensors with similar illumination from pass to pass. source: ]

User: Once a satellite is placed in orbit, it will remain there indefinitely. True or false?

User: A satellite is always being pulled by gravity. True or false?

User: Satellites can focus on specific latitudes using: North-South orbits East-West orbits oblique orbits none of the above

Weegy: NONE OF THE ABOVE {A satellite in a direct orbit with an orbital period less than one day will tend to move from west to east along its ground track.}
