1. A magnetic sensor array for measuring a magnetic field generated by a magnetic source, the magnetic sensor array comprising:

  • a planar substrate having an upper surface, the planar substrate including only one set of magnetic sensors, the set of magnetic sensors consisting of;

    a first three-dimensional magnetic sensor secured to the upper surface of the substrate at a central location;

    a plurality of second three-dimensional magnetic sensors each secured to the upper surface of the substrate at a first distance from the first three-dimensional magnetic sensor; and

    a plurality of first one-dimensional magnetic sensors each secured to the upper surface of the substrate at a second distance from the first magnetic sensor that is greater than the first distance, the plurality of first one-dimensional magnetic sensors being configured to measure a Z-component of the three-dimensional magnetic flux density of the magnetic field at a point in space.
