【Abstract】 The coning motion in SINS with three-axis dithered laser gyroscope is discussed. The classic method of coning error estimation is described; and based on this, a more effective method is given, i.e. the method of Lissajous figures. The Lissajous method is more effective and simple, and it’s more close to engineering application. All the above is verified by experiments.更多还原
