What is non geostationary orbit?
Non-geostationary (NGSO) satellites occupy a range of orbital positions (LEO satellites are located between 700km-1,500km from the Earth, MEO satellites are located at 10,000km from the Earth), and do not maintain a stationary position, but instead move in relation to the Earth’s surface.
What are the advantages of a non geostationary satellite?
The advantages of NGSO systems are the lower latency, smaller size and lower losses in comparison to GEO satellite systems and that when a constellation is shaped a global coverage can be achieved.
What is the difference between geostationary satellite and non geostationary satellite?
The only difference between the two is that while a geosynchronous satellite may or may not be following an inclined orbit (with respect to the equatorial plane), a geostationary satellite has to follow a non-inclined orbit.
What is MEO in satellite communication?
A medium Earth orbit (MEO) is an Earth-centred orbit with an altitude above a low Earth orbit (LEO) and below a high Earth orbit (HEO) – between 2,000 and 35,786 km (1,243 and 22,236 mi) above sea level.
What is the function of geostationary satellite?
Geostationary satellites are a key tool for scientists to monitor and observe the Earth’s atmosphere. They are called geostationary due to their movement. Geostationary satellites orbit around the Earth at the same rate as the Earth rotates so that the satellites are over the same spot on Earth all the time.
What is the difference between a geosynchronous and a non geosynchronous orbit?
While geosynchronous satellites can have any inclination, the key difference to geostationary orbit is the fact that they lie on the same plane as the equator. Geostationary orbits fall in the same category as geosynchronous orbits, but it’s parked over the equator.
What is MEO and LEO?
orbits: low Earth orbit (LEO), medium Earth orbit (MEO), and geostationary or geosynchronous orbit (GEO). LEO satellites are positioned at an altitude between 160 km and 1,600 km (100 and 1,000 miles) above Earth. MEO satellites operate from 10,000 to 20,000 km (6,300 to 12,500 miles) from Earth.
