Voltage resistance testing often needs to be carried out under specific environmental conditions, such as high pressure and high temperature. These complex environments may interfere with the test equipment and calibration process, thus affecting the accuracy of calibration results. Therefore, it is necessary to ensure that the tester can adapt to various environmental conditions and make calibration adjustments accordingly. Therefore, a multi-calibration method based on the BP neural network is proposed to calibrate the error of the indicator value of the voltage tester. The power input and output characteristic function of the withstand voltage tester is established, and the output of each layer is described as the input of the BP neural network. Based on the adjustment results, multiple calibration steps for the measuring error of the voltage tester are designed. The experimental results show that the method can calibrate the measuring error of the voltage tester at different positions at the same time, and the application effect is good.

“…The general aircraft aeromagnetic interference compensation model proposed by Tolles and Lawson has been gradually developed to the classical Tolles‐Lawson equation (Bickel, 1979a, 1979b; Leach, 1980; Tolles & Lawson, 1950). In order to solve it, Leliak (1961) proposed a method to calculate the aeromagnetic interference compensation coefficients based on the aircraft's pitch, roll, and yaw maneuvering flight actions, and it has been in use since then (Du et al., 2019; Feng et al., 2022; Fitzgerald & Perrin, 2015; Hardwick, 1996; Hezel, 2020; Qiao et al., 2021; Rice and Joseph, 1993; Zhou et al., 2014).…”

The aeromagnetic measurement technology, which can be implemented in areas difficult for ground magnetic measurement, such as desert, glacier, virgin forest and land-sea junction, is one of the most effective means to quickly and economically obtain high-precision geomagnetic data. It has important applications in the fields of geomagnetic navigation background field construction, mineral resources development, seismogenic sources tracking, hidden tectonic and volcanic structures revealment, etc.

In aeromagnetic measurement, accurate compensation for the interference magnetic field generated by the aircraft platform due to the aircraft maneuvering in the Earth's magnetic field is an important prerequisite for the accurate indentification of the magnetic anomaly signal of the detection target. The flaws of the traditional calibration flight scheme in aeromagnetic interference compensation are firstly analyzed, and then an improved scheme is proposed, featuring smaller calibration flight areas, more simplified maneuvers, shorter flight route and less influence from the magnetometer's direction. The improved scheme can enhance the robustness of the aeromagnetic interference compensation matrix, and improve the compensation efficiency, and thus both the solved magnetic compensation coefficients and compensation effects are significantly improved. The experimental results of aeromagnetic interference compensation in an area of Inner Mongolia of China show that the average accuracy of the repeated survey lines, which are compensated by the improved scheme, can be increased by 5 nT and 3 nT, respectively, compared with the uncompensated results and the results compensated by the traditional scheme. Therefore, the effectiveness and superiority of the improved calibration flight scheme is fully proved.
