What is the time period of a geostationary satellite?
Geostationary satellite is one of the artificial satellites, which revolves around Earth’s equator above 22,236 miles in a geostationary orbit. It has an orbital period equal to Earth’s rotational period of 23 hours and 56 minutes, which is about one day on earth.
Why do geostationary satellites have a short lifespan?
The useful lifetime of geosynchronous orbit satellites averages about fifteen years – a limit primarily imposed by the exhaustion of propellant aboard. Low Earth Orbit satellites may have even shorter life spans, due to the increased atmospheric drag and friction to which they are subject.
What is the period of a geostationary satellite in seconds?
Given that a geostationary satellite is, by definition, stationed over a single point on the Earth’s surface, its period is exactly that of the Earth’s. That’s to say, a geostationary satellite’s period is presently 23 hours, 56 minutes and four seconds, give or take small errors.
What is the time period of a satellite?
The period of a satellite is the time it takes it to make one full orbit around an object. The period of the Earth as it travels around the sun is one year. If you know the satellite’s speed and the radius at which it orbits, you can figure out its period.
What does the period of a satellite depend on?
The orbital period of a satellite depends on the mass of the planet being orbited and the distance of the satellite from the centre of the planet.
What is the lifespan of a geostationary and a non geostationary satellite?
The average life span of a LEO satellite is approximately 5 years, but the average life span for a GEO satellite is approximately 8 years.
How long do communication satellites last?
A satellite launched in the 1990s was designed to operate for an average 12 years, a life expectancy that by the 2000s increased to 15 years. Many continue to operate for 18 years or more, but 15 remains the prevailing design life.
Why do geostationary satellites orbit 24 hours?
Geostationary orbit basics As the height of a satellite increases, so the time for the satellite to orbit increases. At a height of 35790 km, it takes 24 hours for the satellite to orbit. This type of orbit is known as a geosynchronous orbit, i.e. it is synchronized with the Earth.
What is the period of revolution of satellite?
The period of revolution of an Earth’s satellite close to the surface of Earth is 90min.
Does time period of artificial satellite depends on its mass?
