the GPS receiver to the navigation control unit to adjust vehicle position.

DESCRIPTION
The GPS can't be utilized due to a faulty
GPS receiver, open in the wire, or other
fault or interference.
GPS function is normal. The satellite
signals received by the GPS are too few to
detect the vehicle position.
The longitude and latitude of the vehicle
position can be detected. (Less precise
than detection in three dimensions)
The longitude, latitude and the altitude of
the vehicle position can be detected. (More
precise than detection in two dimensions)
