GPS devices rely on signals from satellites to determine their location. These signals are already very weak when they reach the Earth’s surface and require a clear line of sight to multiple satellites.
When a device is inside a building, especially one made of concrete, steel, or other dense materials, those signals are blocked or reflected. This prevents the device from establishing a proper GPS fix. As a result, the device may show “no GPS” or display inaccurate positioning until it has access to a clear view of the sky.
This is normal behavior for all GPS-enabled devices and typically resolves as soon as the unit is moved outdoors.
To help your devices establish a reliable GPS fix, we recommend the following:
Store devices near windows or in open areas whenever possible.
Avoid storing devices in metal or concrete structures overnight, as these materials block signals the most.
When first powering on, place the device outdoors with a clear view of the sky for a few minutes to allow it to lock onto satellites.
If moving a device from indoors to outdoors, give it a short time to re-establish its GPS fix before use.
By following these practices, you can minimize issues with GPS performance and ensure your devices are ready for use when needed.
