OMG he is totally right thanks so much

You can get better service if you don't change screen names.

By using satelite images

are you sure this is correct

OMG THANKS SO MUCH

are u sure

The correct answer is A. Global positioning systems (GPS) use signals from a network of satellites to determine latitude and longitude on Earth's surface.

To understand how GPS works, let me explain the process. GPS satellites orbit the Earth and continuously transmit signals. A GPS receiver on the ground picks up these signals and calculates the distance to each satellite based on the time it took for the signals to reach the receiver. The receiver typically needs signals from at least four satellites to accurately determine its position.

GPS receivers also take into account the elevation, or altitude, but this is mainly to calculate the three-dimensional position (latitude, longitude, and altitude) accurately. The elevation data adds the Z-axis to the usual X and Y coordinates, allowing for more precise positioning.

So, in summary, GPS does utilize elevation information in Earth's system, along with signals from a network of satellites, to find latitude and longitude.

This doesn't make any sense. Please check for typos and repost.
