Triaxial magnetism detecting apparatus and satellite

A satellite having a triaxial magnetism detecting apparatus, the apparatus comprising:

• a body;
• a retaining member formed of a non-magnetic material, the retaining member being fixed on the body;
• a magnetism detector detecting a magnitude of a magnetic field component along one of X, Y, and Z axes, the magnetism detectors being fixed respectively on side faces of the retaining member that are perpendicular to a face being in contact with the body;
• and
• a circuit board to which an output signal of the magnetism detector is transmitted, the circuit board being fixed on the body,
• wherein the retaining member and the circuit board are separated from each other, and a terminal pin that electrically connects the magnetism detector and the circuit board is fixed to the retaining member between the magnetism detector and the circuit board,
• wherein a reference face of the triaxial magnetism detectors matches a reference face of the satellite.
