What are the different artificial satellites launched into orbit?

The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.


Why does a GPS have an antenna?

A GPS device needs an antenna to receive signals from satellites orbiting the Earth. The antenna picks up signals transmitted by these satellites to determine the device's location on the Earth's surface.

How many satellites are there and how high do they orbit?

There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level. There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level. On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.


Where does gps receiver get its signal from?

A GPS receiver gets its signal from a network of satellites orbiting the Earth. These satellites continuously transmit signals that the GPS receiver uses to calculate its position and determine accurate time information. By receiving signals from multiple satellites, the GPS receiver can triangulate its position with high precision.


How many GPS satellites are there and how many miles are they above the Earth?

There are about 4 that go for one and the four share many. The four gives you an exact location. I am not sure how far away however


How does the gps update stores locations?

Satellites orbiting around earth send information to the GPS , so they detect the change & fix it in their memory.


How was World War 2 fought differently because of GPS?

GPS was not invented for forty years after WWII ended. GPS depends on satellites orbiting the earth. The satellites get there by rocket. The first satellite did not orbit the earth until 1957.


Can I use my GPS system anywhere in the world?

GPS works by triangulating a position based on the locations of satellites orbiting the earth. GPS stands for "global positioning system."


Where does gps reciver get its signal?

A GPS receiver gets its signal from a network of orbiting satellites that transmit location and timing data. The receiver uses this information to calculate its own position on Earth by triangulating the signals from multiple satellites.
