Is the GPS feature on satellite phones worth the investment?

Understanding Satellite Phone GPS

The GPS feature on satellite phones is based on the Global Positioning System (GPS) network, which consists of a constellation of 30 operational satellites orbiting the Earth. These satellites transmit radio signals that can be received by GPS-enabled devices, including satellite phones. To use the GPS feature on a satellite phone, the device must be able to receive signals from at least four satellites, which can take up to 30 seconds.

Accuracy and Reliability

The accuracy of GPS signals on satellite phones can vary depending on the number of satellites in view and the quality of the signal. In ideal conditions, GPS signals can be accurate to within 5-10 meters. However, in areas with heavy tree cover or near large bodies of water, accuracy can be reduced to 100 meters or more. The reliability of GPS signals on satellite phones is also affected by the device’s battery life and the presence of interference from other electronic devices.

Practical Considerations

For users who require accurate location tracking in areas with no cellular coverage, such as hikers, hunters, and emergency responders, the GPS feature on satellite phones is essential. The Garmin inReach satellite phone, for example, has a built-in GPS receiver that can provide location tracking and navigation in areas with no cellular coverage. The device’s battery life is up to 100 hours, and it can send and receive messages via the Iridium network. In contrast, casual satellite phone users who only make occasional calls may not need the GPS feature, as they can rely on their device’s built-in maps and navigation systems.
