How many satellites have been to uranus?
100 and there is life on uranus... go check
How many satellites does the receiver need to be fixed on in order to know it's position?
For an unconstrained solution, you need 4 satellites in view to get a GPS fix. If you know one variable, such as altitude (on a ship, for instance) you can do it with 3.
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.
How many gps satellites must a receiver see?
2.02E04Km * 1E03 m/Km * 1s/2.99792458E08m/s = 6.73799E-02s 20,000Km from Earth converted to meters divided by C in m/s But of course of the roughly 12 of the satellite constellation (of 24) in your hemisphere, some will be much further away than others. (You need a reliable signal from at least four satellites for a useful reading.)
Why do you need weather satellites?
Weather monitoring is the primary function/purpose of weather satellites. They are also used to track different geological, atmospheric and environmental changes that has an impact on the Earth.

How many satellites needed to get a position?
You need 4 to locate a position. There are 24 satellites in use in the sky with 8 spares.
Why are many satellites geo stationary?
Because they only need to transmit to certain parts of the planet. TV relay satellites for example - need to stay in one place to beam the pictures back to earth. If they orbited the earth, the signal would be lost as it crossed the horizon. Another example is the global GPS system. The satellites that provide the information for GPS must remain in one place - otherwise they wouldn't give accurate information to the user.
How does the US protect its satellites?
We don't need to protect our satellites because their is not yet warfare in space where our satellites are.
What do you have to have to make a GPS work?
GPS devices receive signals from several Global Positioning Satellites, which orbit the earth. The device uses the difference in timing from the signals to calculate its own position. I don't remember, but I think you can get a position with signals from 4 satellites, so you would need to have a clear signal from the satellites in order for the device to calculate its position.

Why you add a positive voltage to the ac signal to allow a transistor to amplify ac signal?
It depends on how you bias the transistor. If you ground the emitter, which is very common, you will need to offset the input signal so you can amplify the full voltage swing.
Why does g.p.s. need 4 satellites?
triangulation
In the movie Independence Day why do the aliens use and need Earth's satellites?
The aliens need to use earth's satellites so that they can coordinate their invasion efforts.
Which Wireless Router Repeater or Expander do you need to boost your wifi signal that is under 100 and doesnt need to be be plugged in by ethernet?
Hawking HWREN1 Hi-Gain Wifi extender works just like it says- doubles the existing connection signal… My large house has full bar signal everywhere, no complaints from me.
How many gps satellites are required to pinpoint your location on earth surface?
To determine latitude and longitude the minimum number of satellites that the receiver must lock onto is three. To also determine elevation the minimum number of satellites that the receiver must lock onto is four. If the receiver can lock onto more satellites then it can improve the calculations to get a more precise location.
How many satellites do you need to find your location?
A single satellite can only give you relative location. 3 satellites can give a 2-D positioning/location that includes longitude and latitude. 4 satellites can give a 3-D positioning/location that includes longitude, latitude and altitude. Only 4 satellites can give you absolute location.
