Workflow

The following steps should be followed in order to calibrate the Velocity & Displacement Engine before starting to use the GR receiver
on a new site for displacement detection:
•
Access the web interface page GNSS management > Velocity & Displacement Engine.
•
Enable the Velocity & Displacement Engine by ticking the Enable Engine check box.
•
Use the Save changes button to start the velocity threshold computation process.
•
Wait 24 hours until the velocity threshold computation has finished.
•
Go back to the web interface page GNSS management > Velocity & Displacement Engine.
•
Compare the computed velocity thresholds with the default thresholds. Take over the computed threshold values if they are
different than the default thresholds. To do this there are two options:
•
Use the Get computed thresholds button
•
Enter the computed values (or other values) into the fields in table Current thresholds used for displacement
detection
•
Apply the new velocity thresholds by using the Save changes button. This will also restart the Velocity & Displacement
Engine.

Event log messages

The following event log messages will appear when the state of the Velocity & Displacement Engine is changed:

Receiver setup

Receiver Setup: Overview

•
Velocity & Displacement Engine is disabled.
•
If restarted, the default velocity thresholds will be used.

started
When threshold computation period of 24 h has
finished
Velocity & Displacement Engine has been reset.
Start of displacement has been detected.
End of displacement has been detected.
Calculated displacement is reported to the user.
