What is essential when utilizing GPS technology to trace a cell phone?

When utilizing GPS technology to trace a cell phone, having a built-in GPS chip is crucial because this component allows the device to receive signals from satellites to determine its precise location. The GPS chip utilizes a network of satellites to triangulate the phone's position, providing accurate and real-time location data. This functionality is foundational to GPS tracking; without it, the GPS system cannot operate, rendering tracing ineffective.

While continuous battery power and a cell tower connection can play roles in maintaining device functionality and communication, respectively, they do not specifically pertain to the core requirement of GPS technology itself. Access to call history, although potentially useful for other investigative purposes, does not contribute directly to the GPS tracing capability. The presence of a built-in GPS chip is the key element that enables location tracking via GPS technology.
