)The height of a satellite's orbit above Earth's surface is calculated using the following formula:
Height = (GM / (2π)^2) * (T^2 / R^3), where GM is the gravitational constant times the mass of Earth, T is the orbital period of the satellite, and R is the radius of Earth plus the desired orbit height.
Calculating a satellite's orbit height is important because it determines the satellite's trajectory and coverage area, as well as its communication and data transmission capabilities. It also affects the amount of fuel needed for the satellite to maintain its orbit.
The higher the orbit height, the slower the satellite's speed will be. This is because the gravitational pull of Earth decreases with distance, so the satellite needs to travel at a slower speed to maintain its orbit.
Yes, the orbit height of a satellite can be changed by using thrusters or other propulsion systems to adjust its speed and trajectory. This is often done to account for changes in the satellite's mission or to avoid collisions with other space objects.
The calculations of satellite orbit height are highly accurate, with a margin of error of only a few meters. However, factors such as atmospheric drag and gravitational anomalies can affect the satellite's actual orbit height, so constant monitoring and adjustments may be necessary.
