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.


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.


How many satellites have been to uranus?

100 and there is life on uranus... go check


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.


How many satellites needed to get a position?

Typically, three satellites are needed to determine a 2D position (latitude and longitude), while four satellites are needed to determine a 3D position (latitude, longitude, and altitude) using GPS technology.


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.


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.


How many satellites does the receiver need to be fixed on in order to know it's position?

A GPS receiver typically needs signals from at least 3 satellites to calculate a 2D position (latitude and longitude) and 4 or more satellites for a 3D position (latitude, longitude, and altitude). The receiver uses the signals from multiple satellites to triangulate its position on Earth.


How many feet you need before you star turning your signal?

500 feet


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.


Why do you need astronauts?

so we can keep our satellites running


Why does it take your tomtom gps device so long to get a valid signal?

Your TomTom GPS device may take a while to get a valid signal if it is searching for satellites or if it is in an area with poor satellite reception, such as within buildings or urban canyons. It can also depend on how long it has been since you last used the device, as it may need time to update its almanac data. Try ensuring a clear view of the sky and giving the device some time to acquire a signal.
