What describes autonomous GPS coordinates?

1. Coordinates dependent on external data

2. Coordinates that require satellite assistance

3. Coordinates obtained independently without additional data

4. Coordinates calculated using manual input

The correct answer is: Coordinates obtained independently without additional data

Autonomous GPS coordinates refer to positions determined directly by a GPS receiver using signals from satellites without needing external correction data or support. This means that these coordinates are obtained using the satellite signals available at the time, and the GPS receiver processes this information to provide an accurate location reading. This process enables the system to work independently, relying solely on the satellites' data without the involvement of additional references or inputs. In contrast, other concepts like coordinates dependent on external data, those that require satellite assistance, or those calculated using manual input do not illustrate the true nature of autonomous GPS. They imply a level of reliance on other systems or interventions, which is not the case with autonomous GPS coordinates that stand alone in their functioning. Understanding this distinction is essential for differentiating between various GPS operation modes.
