Explain how the global positioning system can be used to help find lost children.
google is the first place to try, when all you have is a general question. Then tell us some of your ideas, and we maybe can help focus the discussion. But don't expect us to do your whole assignment, even including the research!
Ok thank you (:
The Global Positioning System (GPS) consists of a network of satellites orbiting the Earth that can accurately determine the location of a GPS-enabled device. It can be a valuable tool in finding lost children by providing real-time location information. Here's how it works:
1. GPS Trackers: GPS trackers are small devices that can be attached to or carried by a child. These trackers use GPS technology to determine their exact location.
2. GPS Signals: The GPS satellites transmit signals that are received by the GPS tracker. A minimum of four satellites is required for accurate positioning.
3. Triangulation: The GPS tracker receives signals from multiple satellites and uses a process called triangulation to calculate its precise location. By measuring the time it takes for the signals to reach the tracker from each satellite, it can determine the distance to each satellite.
4. Position Calculation: Using the distance information from the satellites, the GPS tracker compares the signals and calculates the child's exact location. This information is usually displayed on a map or transmitted to a connected device.
5. Real-Time Tracking: The GPS tracker continuously updates the child's location in real-time. This allows parents or caregivers to track the child's movements and know their exact location at any given time.
6. Alerts and Geo-fencing: Many GPS trackers offer additional features like setting up virtual boundaries known as geo-fences. If the child moves outside the designated area, an alert is triggered, notifying the parents or caregivers.
7. Emergency Help: In case of an emergency or if the child is unable to communicate their location, the GPS tracker can serve as a means to find them quickly. The accurate real-time location information can be shared with authorities or search and rescue teams, enabling them to locate the child efficiently.
It's important to note that using GPS to track a child requires their consent and should be done in compliance with privacy laws and regulations. Additionally, GPS trackers may require a subscription to a service provider for real-time tracking and accessing the location data.
I hope this explanation helps you understand how the Global Positioning System can be used to find lost children.
