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:
Answer & explanation
Answer: (d) 1, 2 and 3
GPS is used for far more than finding locations: its satellite signals carry very precise atomic-clock time, and that timing is used to synchronise mobile networks, banking and financial systems, and power grids. So all three areas are correct.
- ✓ 1. Wireless and communications networks use GPS time to synchronise their operations and to use limited radio spectrum efficiently.
- ✓ 2. Financial networks use GPS time to synchronise systems and to put traceable time tags on financial transactions and billing.
- ✓ 3. Power grids depend on GPS timing for precise synchronisation across the network.
Remember · GPS gives position and precise time. Precise time is used to synchronise communications, financial networks and power grids.
