Why orbit matters at sea
A satellite’s orbit influences distance, apparent motion and how a connection must be maintained.
In 30 seconds
- LEO satellites travel closer to Earth than geostationary satellites.
- A geostationary satellite appears fixed above the equator.
- Real performance also depends on coverage, blockage, capacity and the onboard network.
Make it concrete
Draw a nearby moving light and a distant fixed light. Consider the difference between tracking a moving source and keeping a clear view of a fixed one.
Change a value. Watch the relationship.
Ideal circular Earth orbit: T = 2π√(r³/μ). 1 screen second = 600 orbital seconds. Earth and orbital radii share a scale; the satellite is enlarged. Perturbations are omitted.
Check your understanding
Does a lower orbit by itself guarantee a fast connection for every user?
- LEO satellites travel closer to Earth than geostationary satellites.
- A geostationary satellite appears fixed above the equator.
- Real performance also depends on coverage, blockage, capacity and the onboard network.
