Shortly after the discovery of PSR J1906+0746 , some hints of profile variations were already interpreted as first signs of relativistic spin-precession occuring .
Using observations from the Nançay , Arecibo and Green Bank Radio Observatories , we report here the measurement of pulse profile and polarimetric variations .
Using the Rotating Vector Model , we show that PSR J1906+0746 is likely to be an orthogonal rotator ( \alpha \simeq 80 ^ { \circ } ) .
Fitting our polarimetric data to a precession model , we determined the geometry of the pulsar and found a wide misalignment angle ( \delta = 89 _ { -44 } ^ { +85 } deg , 95 % C.L .
) , although the uncertainty is large .
Assuming this geometry , we constructed the beam maps of both magnetic poles .
