Place where GPS signals can be easily received/Place where GPS signals cannot be received
Easy to receive
• Outdoors under an open sky with good visibility
Difficult to receive
• The smaller the sky, the more difficult it is to receive
GPS signals. In addition, it will also be difficult to
receive GPS signals, if there is something that
obstructs the GPS signals during reception (in
particular, during time zone adjustment).
Examples:
• Between tall buildings
• Near wooded area
• Station/Airport
• Indoors with windows
* GPS
signals cannot be received depending on window glass
type.
Refer to the “
Cannot receive.”
Cannot receive
• The
sky cannot be seen or only part of the sky can be
seen.
• There is something hindering the reception.
Examples:
• Indoors without windows
• Underground
• During passage of a tunnel
• Through special glass with thermal emission shield
effect, etc.
• Close to equipment generating noise or performing
wireless communications
