How the NAV350 deals with sources of error
Overlapping reflectors
On driving around corners or in aisles, two reflectors positioned one after the other will time
and again partially or completely overlap from the point of view of the NAV350. The posi-
tions of these reflectors can then no longer be unambiguously defined and will make the
position calculation by the NAV350 incorrect. The NAV350 detects such a situation and au-
tomatically mutes the usage of the overlapping reflectors.
The situation of an overlapping reflector occurs if the angle between two reflectors from the
point of view of the NAV350 is less than 0.6°. The reflector placement is to be selected for
this case such there are at least 3 further reflectors in the field of view of the NAV350.
