MCQ Detailed View

GPS stands for Global Positioning System, a satellite-based navigation system that allows users to determine their exact location anywhere on Earth. This technology works by using a network of at least 24 satellites orbiting the planet. Each satellite continuously transmits radio signals containing its position and the precise time the signal was sent.

A GPS receiver, such as those found in smartphones, cars, ships, or airplanes, picks up signals from multiple satellites at once. By calculating the time taken for each signal to arrive, the receiver determines its distance from each satellite. Using a process called trilateration, the device then computes its exact position in terms of latitude, longitude, and altitude.

The Global Positioning System was originally developed by the United States Department of Defense for military use but is now available globally for civilian applications. GPS technology has become essential for:

• 
  

  Navigation: Helping vehicles, airplanes, and ships travel accurately.

  
  


• 
  

  Mapping and surveying: Creating precise maps of Earth's surface.

  
  


• 
  

  Disaster management: Locating affected areas and planning rescue operations.

  
  


• 
  

  Everyday use: Guiding drivers, hikers, and smartphone users to their destinations.

  
  

The incorrect options listed in the question do not represent the true meaning of GPS. It has nothing to do with "Global Poles System," "Global PolySiliconium Store," or "Global Position Structure." The universally accepted and scientifically accurate expansion is Global Positioning System.GPS works based on principles of physics, specifically the behavior of radio waves, satellite orbits, and the use of atomic clocks for ultra-precise timing. Without these physics-based technologies, accurate global navigation would not be possible.

Thus, the correct answer is Global Positioning System (Option C).
