Final answer:
Three features of GPS on mobile devices include location accuracy with exact latitude and longitude, travel time calculation between two locations, and real-time updates on location for navigation and services.
Step-by-step explanation:
The Global Positioning System (GPS) on mobile devices has several features that are essential for navigation and location-based services. Here are three key features of GPS in mobile technology:
- Location Accuracy: GPS on mobile devices can provide the exact location in latitude and longitude, with accuracies that can be better than within 50 feet, depending on the device and conditions.
- Travel Time Calculation: Mobile devices with GPS can calculate the driving time between two locations using complex physics equations related to speed, distance, and time.
- Real-time Updates: GPS enables real-time tracking and updates on location, which is particularly useful for navigation apps, ride-sharing services, and other applications that require up-to-date location information.
All of these features leverage a network of 24 satellites that carry precise atomic clocks and work together to provide accurate and dependable positioning data to users worldwide.
