ABSTRACT:
An assembly is configured for sensing its roll orientation, referenced to a roll indexing orientation that is defined by the assembly, so as to produce a roll output signal and for transmitting the roll output signal in a predetermined way. A housing is configured to support the assembly for fixedly co-rotating the assembly with the leading arrangement such that the roll indexing orientation is in a fixed angular offset with respect to any given roll position of the leading arrangement, which fixed angular offset is arbitrarily established between the housing and the leading arrangement. A roll compensation value is established that is a constant in view of the fixed angular offset. In one feature, the roll output signal is received with the steering configuration of the leading arrangement oriented in a particular way, for identifying a corresponding value of the fixed angular offset.
