Your current location greatly influences your ability to obtain GPS information.
A good location for signal reception is outdoors, where the sky is visible and not blocked by buildings, trees, or other objects.
You may experience GPS signal reception problems in the areas like the ones described below. In extreme conditions, you may not be able to receive GPS signals at all.
• Underwater or when being frequently exposed to water
• Where view of the sky above is limited or not visible
• Near trees or buildings
• Near a train station, airport, or other congested location, or in locations where there is heavy traffic and radio wave interference
• Near railway aerial wires, high-voltage lines, TV towers, etc.
• Underground, in a tunnel, or underwater
• Indoors (Reception near a window may be possible.)
• Near wireless communication equipment or other devices that generate electromagnetic waves
GPS satellites are in constant motion, so your current location, time of day, or other factors may cause a delay in the positioning operation or may even make positioning impossible.
If location information can be acquired while the paired phone is in an area where it is unable to receive GPS signals, it means that location information was acquired from network information.
