How many GEO satellites are required to cover the earths surface?

How many GEO satellites are required to cover the earths surface?

Answer: Minimum 3 Satellites are required to cover the earth. Answer: It depends on in which orbit our satellite is located : General cartegoration as LEO MEO GEO ( LOW EARTH ORBIT , MEDIUM,GEOSYNCHRONOUS ) 3 satellites in GEO covers earth .

What is the minimum number of satellites that would allow every location on the equator to see at least one satellite?

This location-finding process in its most accurate form requires eight satellites to be able to see each spot. Because of the limited field of view of each satellite, and the need to have so many satellites overlapping the same view, the GPS network currently contains 32 satellites.

How many geo synchronous satellites are required for uninterrupted world broadcasting?

Solution(By Examveda Team) In theory, 2 satellites in diametrically opposite geo-synchronous orbits could cover the planet. In order for the satellites to communicate, a minimum of 3 would be needed, each at a 60° angle to the others.

How many satellites do we need to get a proper location?

It takes four GPS satellites to calculate a precise location on the Earth using the Global Positioning System: three to determine a position on the Earth, and one to adjust for the error in the receiver’s clock.

Why do we need 4 satellites for GPS?

An atomic clock synchronized to GPS is required in order to compute ranges from these three signals. However, by taking a measurement from a fourth satellite, the receiver avoids the need for an atomic clock. Thus, the receiver uses four satellites to compute latitude, longitude, altitude, and time.

How many LEO satellites are needed for global coverage?

The new age of large LEO constellations Their altitude—more than 35,000 kilometers from Earth—provides them with a wide field of view, allowing operators to cover most of the planet’s surface with three satellites spaced at appropriate intervals.

What is the minimum amount of communication needed?

it requires minimum TWO PEOPLE for any communication to take place. ​ So at least two people are required for any communication to take place.

Which country has the largest number of satellites?

the United States
Of the 3,372 active artificial satellites orbiting the Earth as of January 1, 2021, 1,897 belong to the United States. This is by far the largest number of any single country, with their nearest competitor, China, accounting for only 412.

What is the ideal number of satellites for our planet?

An ideal number of satellites for our planet is 5. 3 in polar orbits at a 120° of interval, and two above the equators at opposite longitudes, at points perpendicular to the planes in which the polar satellites orbit. Now like all other ideal systems, this ideal placing of satell…

How many GPS satellites are there?

According to the US Naval observatory, there are currently 32 satellites in orbit, 27 are in primary use, while the others serve as backups in the event a primary satellite fails. Together the satellites, control centers, and users make up the three segments on which GPS relies : The space segment. The control segment.

How many geostationary meteorological satellites do we need?

The current generation of geostationary meteorological satellite are truely technological marvels. These satellites, however, do not see the poles at all, and to get global coverage of just the equatorial regions, you need a network of 5-6 satellites.

Which orbit is used by the Global Positioning System satellites?

It is the orbit used by the Global Positioning System (GPS) satellites. The second common medium Earth orbit is the Molniya orbit. Invented by the Russians, the Molniya orbit works well for observing high latitudes.
