Explanation:-
It is a global navigation satellite system that provides geolocationand time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.
Many civilian applications use one or more of GPS’s three basic components: absolute location, relative movement, and time transfer.
• Agriculture
• Astronomy
• Automated vehicle
• Cartography
• Cellular telephony.
• Clock synchronization
• Disaster relief/emergency services
• Radio occultation for weather and atmospheric science applications.
• Fleet tracking: used to identify, locate and maintain contact reports with one or more fleet vehicles in real-time.
• Geofencing
• Geo-tagging
• GPS aircraft tracking
• GPS for mining
• GPS data mining.
• Navigation: navigators value digitally precise velocity and orientation measurements.
• Surveying: surveyors use absolute locations to make maps and determine property boundaries.

- Statement 1: GPS is widely used in mobile phone operations.
- Statement 2: Global financial systems increasingly need precise timing systems to schedule and prioritise local and international money transfers, settlements and trades and to provide an audit trail for financial transactions. For example, the time signal provided by the atomic clocks on board the GPS satellites is used by financial institutions worldwide for providing date and time stamps for Electronic Funds Transfers.
- Statement 3: There are reports of GPS spoofing attacks on power grids.
- Thus, all three options are correct. Option D is the most appropriate answer.
