Further Information
• In underground buildings and indoor
parking lots
• Under elevated roads
NOTE
•
Because the GPS satellite is in orbit around the earth, the reception status for
the electromagnetic waves changes depending on their position at that point
in time, even if your vehicle is in the same place. Also, electromagnetic-waves
from satellites near the horizon can be easily influenced by surrounding
obstacles.
•
At times, satellites under the control of the US Department of Defence will
intentionally drop positioning accuracy.
176 Navigation
• In places with a lot of overgrown
trees and so on
• Roads at the base of cliffs and caves
Regarding Errors in Current Position Display
The system displays the vehicle current position based on GPS
information and data from various sensors and road maps. However,
when the radiowave signals from GPS satellites are weak or when
signals are received only from two satellites or less, errors may occur in
the position. Modifying or adjusting the system will not prevent these
errors.
