Geomagnetic Orientation Research Based on Incontinuous Period Sine-wave Estimator

摘要

In this paper,firstly non-liner least squares sinewave parameter estimator is reviewed.Secondly,we present an in-continuous period sine-wave estimator method which we found recently.The convergent area of the in-continuous period is given.In addition,a newly developed geomagnetic orientation system is introduced in this paper.With the method of the incontinuous period sine-wave estimator,the geomagnetic orientation precision is greatly improved.
