gneill said:A geostationary satellite has an orbit that keeps pace with the rotation of the Earth -- a daily rotation -- so that it remains over the same geographical location.

Geostationary orbit means when you look up from Earth it appears the satellite isn't moving.
For this to be the case, the satellite must revolve around Earth at the same period as Earth rotates about it's axis.
This period is 24 hours x 60 minutes x 60 seconds = 86400 seconds.
T = 86400 seconds.
A geostationary orbit is a specific type of orbit around the Earth where a satellite appears to remain stationary in the sky when viewed from a specific location on the ground. This is achieved by placing the satellite at an altitude of around 35,786 kilometers above the Earth's equator and having its orbital speed match the Earth's rotational speed.
Geostationary orbits are important because they allow satellites to provide continuous coverage and communication to a specific location on the ground. This is particularly useful for satellite navigation, weather forecasting, and telecommunication services.
Satellites in geostationary orbit use small thrusters to adjust their speed and direction to counteract any external forces, such as gravity and solar pressure, that may cause them to drift away from their designated position.
One disadvantage of geostationary orbits is that they are limited to the Earth's equatorial region, making them less useful for polar regions. Additionally, the high altitude of these orbits can result in a longer communication delay, which may not be suitable for certain real-time applications.
The lifespan of a satellite in geostationary orbit depends on various factors, such as its design, fuel, and external forces. However, most satellites in geostationary orbit have a lifespan of around 15 years before they need to be replaced or repositioned.
