Which technology does a GPS receiver use to report real-time data?

1. Wi-Fi technology

2. Satellite technology

3. CDMA cell technology

4. GPRS technology

The correct answer is: CDMA cell technology

The GPS receiver relies on satellite technology to report real-time data. This system works by receiving signals from multiple satellites orbiting the Earth, which allows the GPS receiver to determine its exact location based on the time it takes for each signal to travel from the satellite to the receiver. By triangulating data from at least four satellites, it can calculate longitude, latitude, and altitude accurately. Understanding this technology is crucial, as it forms the backbone of GPS functionality in various applications, including navigation, mapping, and tracking. While other technologies like Wi-Fi, CDMA, and GPRS can transmit data, they do not directly provide the real-time positioning data that GPS satellites offer. Each of those options serves different purposes and has different use cases, but they do not fulfill the specific role of delivering the location data that GPS technology provides through satellite signals.
