The absolute minimum number is for momentary complete cover is 4 in a triangular prism shape, but these will not stay in the right positions as they are not in a geostationary orbit.
3 in geostationary orbit will give very bad and failing coverage at the poles and at the outer edge of their footprint
6, 3 in polar orbit and 3 in geostationary orbit will help, but for a practical coverage 4 in geostationary orbit and 4 in polar orbit will be more practical

How many satellites are needed to provide a place on earth?
If the question is regarding finding the latidude and longitude of one point on the earth, the answer is a minimum of three satellites. The method used is called triangulation. If you wish to know the altitude of the point, a minimum of four satellites are needed.

How many satellites orbit the earth 2016?
As of 2016, there were approximately 1,400 operational satellites orbiting Earth. This number includes various types of satellites, such as communication, weather, and scientific research satellites. Additionally, there were thousands of pieces of space debris from defunct satellites and other missions. The total number of objects in orbit, including debris, was estimated to be over 20,000.
How many satellites in sky?
There are thousands of satellites currently orbiting the Earth. The exact number can vary, as new satellites are launched and old ones are decommissioned regularly.
How many satellites are there in the world?
There are currently over 3,000 satellites orbiting the Earth, belonging to various countries and organizations. This number includes both operational and non-operational satellites.

How many satellites do you need to have a full GPS signal?
A minimum of 4 satellites is needed to obtain a full GPS signal. These satellites are used to triangulate your position accurately on Earth.
What is the minimum number of artificial satellites required for communication through the globe is?
3 GEO Satellites located at 120 degrees are required to cover whole of the earth.
What is the minimum number of 'global positioning system' satellites that are observable by a user anywhere on earth?
A user can typically observe at least 4 GPS satellites anywhere on Earth to accurately calculate their position using trilateration.
What is the minimum number of operationsl navstar satellites required for the space segment of gps?
A minimum of 24 operational Navstar satellites are required for the GPS system to work effectively. These satellites are strategically positioned in orbit to ensure global coverage and accurate positioning for GPS receivers on Earth.
How many gps satellites are required to pinpoint your location on earth surface?
At least four GPS satellites are required to pinpoint a location on Earth's surface accurately using trilateration. Three satellites are needed to determine a two-dimensional position (latitude and longitude), while the fourth satellite provides the altitude component.
How many GPS satellites are required to triangulate a plan-form position?
You would need at least three GPS satellites to pinpoint your location. However, you would need a fourth to also identify your elevation.

Are earth satellites only scientific satellites?
No. The earth has one natural satellite ... the moon ... and any number of other satellites whose primary purpose is not scientific (e.g. communication satellites).
Medium earth orbit satellites?
With large number of low-earth-orbit satellites and the geo-synchronous orbit stuffed full of communications satellites, there aren't all THAT many "medium" altitude satellites. But there are some. The GPS navigation satellites, for example, are in highly inclined 12-hour orbits, and an unknown number of military "spy" satellites are in that middle range.
How many satellites orbit the earth 2016?
