Galileo Probe and the EU's Navigation System

The video discusses the Galileo global navigation satellite system, which complements the US GPS. Initially started by private enterprise, the project was taken over by the EU in 2007. Galileo aims to provide more precise positioning than existing GPS, with accuracy down to the meter, including high altitudes. The video explains how GPS works by using signals from satellites to determine exact positions on Earth.

What was the initial plan for the Galileo system's operational year?

• 2017

• 2015

• 2013

• 2010

Who took over the Galileo project after it was abandoned by private enterprise?

• Russian Federation

• European Union

• NASA

• United Nations

How does a GPS system determine your location on Earth?

• By using internet connectivity

• By detecting signals from satellites

• By using a compass and map

• By measuring the Earth's magnetic field

What is required to accurately determine your position using GPS?

• Signals from four satellites

• Signals from one satellite

• Signals from two satellites

• Signals from three satellites

What is a key advantage of the Galileo system over existing GPS technology?

• It provides more accurate measurements at high altitudes

• It uses fewer satellites

• It is cheaper to operate

• It is available only in Europe
