Once the calibration is at a sufficient level, the receiver starts using the sensors in navigation and the
fusion filter status in the ESF-STATUS shows “
FUSION
”. The receiver keeps continuously calibrating
the sensors in the background to improve the quality of the solution.
For optimal performance, repeat the figure-of-eight pattern until the ESF-ALG shows “
FINE
”. Before
the actual testing, continue driving curves and straight segments until all sensors in the ESF-
STATUS report “
CALIBRATED
”.
☞
Refer to the ZED-F9K Integration manual [1] for more information about the sensor calibration.

Testing the receiver
The device is now ready for actual test drives. For replaying and analyzing the test drives afterwards,
record the data into log files with u-center.
To collect a proper log file with sufficient information:
1.
Open u-center.
2.
Select the device with
Receiver > Connection > COMXX.
3.
Enable UBX messages according to what needs to be monitored.
4.
Enable debug messages with the debug message button (Figure 1). This step is optional, but
necessary for investigation of issues.
5.
Start recording with the record button (Figure 1).
6.
When prompted to poll the receiver configuration, select the correct receiver generation, and click
“Yes”.
7.
Perform the test drive.
8.
To stop recording, click the eject button (Figure 1). The log file will be saved automatically.

Analyzing the log files
After collecting data over the test drives, u-center can be used to replay and analyze the logs in several
ways:
•
Checking the general receiver status
•
Monitoring data in individual messages
•
Using the chart view to monitor certain parameters over time
To replay a log,
1.
Open u-center.
2.
Open a log using
File > Open…
3.
Use the log playback controls (Figure 2) to play, pause and move the current time in the log file.
4.
Open different views from the
View
menu.
☞
Refer to the u-center User guide [7] for more information about its features.
