Q55 (IAS/2018) Science & Technology › ICT, AI, Cybersecurity & Emerging Tech › Satellite and navigation systems Official Key

In which of the following areas can GPS technology be used ? 1. Mobile phone operations 2. Banking operations 3. Controlling the power grids Select the correct answer using the code given below :

Result
Your answer: —  ·  Correct: D
Explanation

The correct answer is option D because GPS technology can be used in all three areas mentioned.

GPS has become a handy tool to find out exact locations[1], which directly supports its use in mobile phone operations for navigation and location-based services. Global Positioning Systems (GPS) can discover the shortest routes for transporting goods[2], demonstrating its practical application in various operational contexts.

For banking operations, GPS technology is used for location-based security, ATM locators, fraud detection by tracking transaction locations, and timestamping of transactions. In power grid control, GPS provides precise time synchronization critical for coordinating power distribution across the grid, enabling real-time monitoring and automated fault detection systems.

While the documents explicitly confirm GPS usage in mobile operations and general technological applications, GPS's role in providing accurate timing and location data makes it essential for both banking security systems and power grid synchronization. Therefore, all three applications—mobile phone operations, banking operations, and controlling power grids—utilize GPS technology, making option D the correct answer.

This is a classic 'Application of Technology' question. While Statement 1 is direct NCERT geography, Statements 2 and 3 test your understanding of GPS as a 'Timing' tool, not just a 'Positioning' tool. The strategy here is not to find a specific book line, but to apply the 'Possibility Heuristic' common in Science & Tech: if a technology provides data (location/time), any sector needing that data can theoretically use it.

How this question is built

This question can be broken into the following sub-statements. Tap a statement sentence to jump into its detailed analysis.

Statement 1
Can GPS technology be used in mobile phone operations (for location services and navigation)?
Origin: Direct from books Fairness: Straightforward Book-answerable

“transformed into computer cartography. Technology has enabled scholars to handle large quantum of data. The internet provides extensive information. Thus, the capacity to attempt analysis has increased tremendously. GIS has further opened vistas of knowledge. GPS has become a handy tool to find out exact locations. Technologies have enhanced the capacity of attempting synthesis with sound theoretical understanding. You will learn some preliminary aspects of these techniques in your book, Practical work in Geography – Part I (NCERT, 2006). You will continue to improve upon your skills and learn about their application.”
Why this source?
  • Explicitly states GPS is a 'handy tool to find out exact locations' — directly supports use for location services.
  • Frames GPS as a practical technology used for locating positions, which is the core capability used by phone location features.

“Technology means the application of scientific knowledge. For example, a camera converts light into electrical signals to create a digital image. Any production-related activity uses some form of technology. Some early forms of technology that have existed since ancient times are still in use today. Today, newer and advanced technological developments are applied in various areas, making our lives easier. For example, payments can be made at the click of a button through UPI (Unified Payments Interface); farmers can get advance weather updates; Global Positioning Systems (GPS) can discover the shortest routes for transporting goods, and so on. Fig. 7.19.”
Why this source?
  • Describes GPS as able to 'discover the shortest routes' — directly supports navigation use-case.
  • Shows GPS applicability to route-finding, the same function mobile phone navigation apps perform.

“The communication service is defined as the transmission of messages, particularly sending and receiving information. Development of satellite communication and mobile technologies gives prominence to this sector.”
Why this source?
  • Links development of satellite communication with mobile technologies, implying mobile devices can use satellite-based services.
  • Provides contextual support that mobile technology and satellite-based systems operate together in the communications sector.
