“…Two or more IBs perform outphase oscillations, which makes it possible to use the differential measurement mode and to counteract inertial accelerations [30]. The most famous imple mented MEMS gyros with two IBs (two body) include products by Analog Devices such as ADXRS150 (LL type) [31], Sensonor such as SAR500 (RR type, But terflyGyro™) [32] and tuning fork gyro TFG by Draper Laboratory (LR type) [21]. In these gyros, all the IBs are located in one plane.…”

“…Maytagging has been widely applied in various methods of north finding angle detection, such as the two-point method, four-point method, and multiposition method. (6)(7)(8) It is simple to operate and is widely employed in practical applications. However, this method will increase the error caused by the rate random walk (RRW), which conflicts with the angular random walk (ARW).…”

The north finder has been widely used in precision guided weapons, unmanned aerial vehicles (UAVs), and other device. In this paper, a north finder based on a low-cost microelectro-mechanical system (MEMS) gyro is proposed. In order to reduce the substantial bias effect on the gyro's north finding angle, a bidirectional carouseling method is applied. To improve the north finding accuracy, the phase difference between the turntable rotation rate and the gyro output is used. After the calculation of the phase difference, a five-order Butterworth filter is chosen to eliminate the gyro high-frequency noise. Experimental results demonstrate that the proposed method based on the phase difference can effectively improve the north finding accuracy by 50% compared with the traditional carouseling method.
