That's key to detecting precession, because during each eclipse astronomers can determine the precise angle of the radio signal and therefore the pulsar's wobble over time.
Careful observations should also detect other relativistic effects, including the precession of the pulsar's own rotational axis due to the effect of the pulsar's spin on the surrounding space-time.
