Correction of Three Sensors in a Magnetic Field Gradiometer
Journal of Sensors, 2022 A magnetic sensor array is usually used for weak magnetic target detection. This paper presents a vector second-order gradiometer that is arranged in a vertical structure. The measurement accuracy of the gradiometer is affected by the error of each three-axis magnetometer (TAM) and the misalignment error between TAMs.

Magnetic Field Coils for Gradiometer Balancing
IEEE Transactions on Applied Superconductivity, 2007 We present a design of a compact set of biplanar coils which produces magnetic fields of eight different profiles for the purpose of gradiometer balancing. The magnetic field profiles correspond to uniform magnetic fields in three orthogonal directions and five linearly independent first-order gradients.

Maximum-variance gradiometer technique for removal of spacecraft-generated disturbances from magnetic field data [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2020 In situ measurement of the magnetic field using spaceborne instruments requires a magnetically clean platform and/or a very long boom for accommodating magnetometer sensors at a large distance from the spacecraft body.

Gradiometer-Based Magnetic Localization for Medical Tools
IEEE Transactions on Magnetics, 2023 Remote magnetic navigation offers various possibilities for medical interventions. Magnetic catheters can be wirelessly steered with high precision and accuracy through complex structures, as they are generally more dexterous and flexible than their manually steered counterparts. Position feedback is essential for many tasks. However, most commercially

Development of precise off-diagonal magnetoimpedance gradiometer for magnetocardiography
AIP Advances, 2017 We have developed a precise off-diagonal magnetoimpedance (MI) gradiometer that can operate in an unshielded environment and at room temperature with 200 pT root-mean-square noise in a 100 Hz bandwidth.

Archaeological Prospection, EarlyView.ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.
