A measurement system is a source of streaming data. Best supported is data of type timeseries of double values. A double-timeserie is called channel.

Multiple measurement systems can be used, even more than one of the same type.

If Rotations should be read in the form of 3×3-Matrixes from the sensors but the sensors does not define such data types, than it is automatically asked for roations in quaterion format. The quaternions are than automatically converted into matrixes.
