The invention discloses a multi-sensor position measurement system mainly comprising a base, a carrier and a modular component, the carrier is provided with a first signal array and a second signal array. The modular component is disposed on the base, and comprises two Hall sensors for sensing magnetic field changes of the first signal array, two magnetoresistive sensors for sensing magnetic field changes of the second signal array, and a first state sensor having a marking unit disposed on the carrier and a sensitive element disposed on the base for sensing signals generated by the marking unit for subsequent reference signal generation, connection of measurement results between other sensors, and identification of homing direction.
