Vehicle compensation

| Sensor disposal for vehicle compensation |
By mounting the OVHWizard,
the measurement of the contact wire position in relation to the top edge
and centre of the rail is influenced directly by the movement of the measuring vehicle.
The measurement can be made without compensating these errors when moving
very slowly (up to approx. 10 km/h) or when the demands on the measuring accuracy
are low.
For high precision measurements when the vehicle is moving the OVHWizard offers compensation inputs for the vertical (suspension) and horizontal (track clearance) movement of the vehicle as well as for the rolling angle around a known centre of rotation. Compensation takes place directly in the measuring system.
