A large area streamer tube detector (128m^2), located within the KASCADE- Grande Experiment, has been built with the aim to identify muons (E>0.8GeV) and their direction in extensive air showers. Besides the investigation of the muon pseudorapitity in EAS, the application of the tracking detector in reconstructing the muon production height is evaluated. The combination of the muon production height with shower parameters from the surface array is demonstrated. Almost model independent energy spectra for different mass groups are obtained. The muon production height distributions are reproduced differently by different interaction models which are employed in the air-shower simulation code CORSIKA.
