[Abstract]:Rotating accelerometer gravity gradiometer plays an important role in energy exploration, geodesy and other fields, and has developed rapidly in recent years. However, the mismatch of accelerometer scale factor causes great interference to the measurement accuracy of gradiometer. In this paper, the adjustment method of accelerometer scale factor is designed based on the simulation system of rotating accelerometer gravity gradiometer. The main research contents and achievements are as follows: the simulation system of rotating accelerometer gravity gradiometer is designed, including the software programming of the hardware in the simulation system and the design of the real-time initial phase solution module at the data receiver. The design of the feedback module of the scale factor adjustment at the data receiving end, the design of the real-time receiving feedback data module of the data sender, the design of the scale factor adjustment module and so on. The results of system performance test show that the modules can be connected with each other, the processing is correct, the interface of the software is friendly, and it is simple and easy to operate. The adjustment method of scale factor theory is introduced in detail, including the real-time solution method of initial phase, the method of data demodulation and the method of PID control feedback scale factor adjustment. This method can correctly realize the adjustment of scale factor. Two sets of data as source data and four sets of data as source data are used to adjust the scale factor of accelerometer. The two methods are used to simulate the gravity gradient simulation system platform respectively. the experimental results show that the two methods can adjust the scale factor of accelerometer and meet the accuracy requirements. In this paper, the adjustment method of accelerometer scale factor based on gravity gradiometer simulation system has important reference value for the development of rotating accelerometer gravity gradiometer.
