Describe the purpose of GPS receivers, and why manufacturers embed them in smartphones.

GPS receivers serve a crucial role in providing location-based services. Here's a step-by-step explanation:

1. Purpose of GPS Receivers: GPS (Global Positioning System) receivers are designed to locate one's position anywhere on earth. They do this by receiving signals from a network of satellites orbiting the earth. By calculating the time it takes for the signal to travel from the satellite to the receiver, the GPS can determine the distance to each satellite and thus pinpoint the receiver's exact location.

2. Embedding GPS in Smartphones: Manufacturers embed GPS receivers in smartphones for several reasons. The primary reason is to provide location-based services. These services include navigation (like Google Maps), location-based search (for restaurants, landmarks, etc. nearby), social media check-ins, and even tracking lost or stolen phones. Additionally, many apps require location access to function correctly, such as weather apps, fitness trackers, and ride-sharing services.

In summary, GPS receivers are embedded in smartphones to provide a wide range of location-based services that enhance the functionality and user experience of the device.
