Demodulator probe secondary localization method

The demodulator probe secondary positioning method of offshore oil earthquake starts with the looking for a demodulator probe location. Calibration of the demodulator probe based on the data of the location's data, if it is pulled in the best position, the coordinate of the point is the actual coordinate of the demodulator probe. It improves the existing speed over 7 times, with positioning precision significantly improved. It can reduce working load of relevant personnel, saving a lot of working time.
