Quick Answer
Most satellite phones come with built-in GPS capabilities, allowing users to access location information and navigate off-grid areas without reliance on cellular networks. However, users need to purchase a specific GPS-enabled satellite phone model, such as the Garmin inReach or DeLorme, which usually costs around $1,000-$2,000. Some models also require a subscription to a satellite messaging service.
Understanding Satellite Phone GPS Capabilities
Satellite phones with GPS capabilities use a combination of satellite signals to provide location information. These phones typically use the Global Positioning System (GPS) constellation, which consists of 24-32 operational satellites orbiting the Earth at an altitude of approximately 20,000 km. The GPS signals are received by the satellite phone’s GPS receiver, which calculates the user’s location based on the time delay between the signal transmission and reception.
Selecting a GPS-Enabled Satellite Phone
When selecting a GPS-enabled satellite phone, users should consider the phone’s antenna design, GPS receiver sensitivity, and the satellite constellation it uses. For example, the Garmin inReach uses the Iridium satellite constellation, which provides global coverage with 66 low Earth orbit satellites. The DeLorme inReach Explore+ uses a combination of Iridium and GPS signals, allowing for more accurate location tracking. Users should also consider the phone’s battery life and durability in harsh environments.
Using a Satellite Phone for Navigation
To use a satellite phone for navigation, users need to pair the phone with a compatible GPS-enabled device, such as a handheld GPS unit or a smartphone app. The phone will transmit the GPS location data to the device, which will display the user’s location on a map. Users can then use the device to navigate to their destination, track their route, and access additional features such as altitude and speed tracking.
