Output of position and additional information
Outputs of the NAV-LOC system are:
Current position (X,Y) in the coordinate system of the reference
map
Current yaw angle in the coordinate system of the reference map
Pose quality of the detected position
Status of the localization
- initializing:
localization initializes to the stated position
- halted:
localization detects that the vehicle is stationary
- running:
localization continuously calculates the vehicle po-
sition
A time stamp in milliseconds is also output in the telegram for every position output.
Map dimensions:
X: 0.0 – 60.0 m
Y: 0.0 – 50.0 m
Grid size: 10.0 m
Orientation angle:
Example for position output:
X-coordinate: 24 m
Y-coordinate: 24 m
Orientation angle: 0°

Pose quality
In addition, a quality assessment of the detected “pose quality” position is output which specifies the
reliability of the pose result. Its values are represented in a range of 0 to 100.
NOTE
The quality value does not show the accuracy of the pose, but the values indicate the stability of the
localization process, which led to the pose result.
Individual outliers should be observed, but should not cause immediate reaction.
The following ranges can be used for orientation:
High level of accuracy: typ. 0 – 30
A high level of accuracy with the data given below in the data sheet requires optimum application con-
ditions.
For accurate localization as defined by the data sheet, the average value should stay below 30.
