180 - Device Reference Point (DRP) to Ground distance Request changes
DefinitionThis DDI is used to specify the distance from the Device Reference Point (DRP) down to the ground surface. The DRP to Ground DDI shall be attached only to the Device Element (DET) with element number zero.
CommentDepending on the application it might be required to know the distance of a device element down to the ground. All device element offsets refer to the DRP which is the centre of the device coordinate system and usually not at the ground surface. For instance the DRP of a tractor is the centre of the rear axle. In this case the distance from a GPS receiver (DET of type navigation reference) attached on the roof of the cab is calculated through sum up the Z-offset of the DET and the distance of the DRP to ground. The value of the DRP in this case is equivalent to the radius of the rolling wheel which is attached on the tractor rear axle.
