A method of monitoring a conveyance apparatus within a conveyance system, the method comprising: detecting, using a magnetometer, a first magnetic signature within the conveyance system at a first time, the magnetometer being attached to the conveyance apparatus; comparing the first magnetic signature detected to a plurality of magnetic signatures contained in a magnetic signature lookup table, wherein each of the plurality of magnetic signatures in the magnetic signature lookup table are assigned to a specific location along a conveyance path of the conveyance system; and determining a location of the conveyance apparatus at the first time by matching the first magnetic signature to one of the plurality of magnetic signatures; wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car, wherein the conveyance path is an elevator shaft of the elevator system, and wherein the specific location along a conveyance path of the conveyance system is a landing; further comprising: conducting a learn run through the conveyance path to learn the plurality of magnetic signatures contained in the magnetic signature lookup table; wherein the learn run further comprises stopping at each of a plurality of specific locations along the conveyance path to learn a magnetic signature at each of the plurality of specific locations for the magnetic signature lookup table; and characterised in that in the event that a magnetic signature of the earth cannot be differentiated amongst multiple landings, the method further comprises placing a magnet at that location along the elevator shaft. detecting, using a magnetometer, a first magnetic signature within the conveyance system at a first time, the magnetometer being attached to the conveyance apparatus; comparing the first magnetic signature detected to a plurality of magnetic signatures contained in a magnetic signature lookup table, wherein each of the plurality of magnetic signatures in the magnetic signature lookup table are assigned to a specific location along a conveyance path of the conveyance system; and determining a location of the conveyance apparatus at the first time by matching the first magnetic signature to one of the plurality of magnetic signatures; wherein the conveyance system is an elevator system and the conveyance apparatus is an elevator car, wherein the conveyance path is an elevator shaft of the elevator system, and wherein the specific location along a conveyance path of the conveyance system is a landing; further comprising: conducting a learn run through the conveyance path to learn the plurality of magnetic signatures contained in the magnetic signature lookup table; wherein the learn run further comprises stopping at each of a plurality of specific locations along the conveyance path to learn a magnetic signature at each of the plurality of specific locations for the magnetic signature lookup table; and characterised in that in the event that a magnetic signature of the earth cannot be differentiated amongst multiple landings, the method further comprises placing a magnet at that location along the elevator shaft. conducting a learn run through the conveyance path to learn the plurality of magnetic signatures contained in the magnetic signature lookup table; wherein the learn run further comprises stopping at each of a plurality of specific locations along the conveyance path to learn a magnetic signature at each of the plurality of specific locations for the magnetic signature lookup table; and characterised in that in the event that a magnetic signature of the earth cannot be differentiated amongst multiple landings, the method further comprises placing a magnet at that location along the elevator shaft.
