“…When the time went into 1990s, NGIMU developed again due to the high cost of the gyroscope with high precision. In 1991, Algrain affirmed that there are at least six accelerometers by which we can compute the linear acceleration and the angular acceleration of a rigid body [4]. In 1994, Chen presented a novel design of sixaccelerometer configuration [5].…”

Non-gyro inertial measurement unit (NGIMU) uses only accelerometers replacing gyroscopes to compute the motion of a moving body. Use the traditional accelerometer configurations for reference, a novel nine-accelerometer configuration of NGIMU is proposed with its mathematic model constructed. This configuration can acquire the expressions of the angular accelerations directly and avoid calculating the differential poly-equation. To confirm the effectiveness of the design, the experiment system is set up and the DSP data processing circuit is also done. In addition, the experiments of the angle estimating are performed and the results show that the design can reflect the trend of the angle changing with high precision to some extent.

“…We hope to use small accelerometers with low cost to replace the gyroscopes to realize navigation for the missile. So the nongyro inertial measurement unit (NGIMU) using accelerometers is studied extensively to determine the posture of a rigid body [1][2][3][4][5][6][7][8][9].…”

Then Chen et al 3 proposed the six-accelerometer (6A) cubic configuration, which has one accelerometer at the center of each surface of a cube with its sensing direction along the respective surface diagonal.…”

A novel inertial measurement unit scheme with five accelerometers and two gyros (5A2G) is proposed in this paper to achieve high precision measurement in high dynamic environment. The three channels are decoupled during the angular velocity calculation procedure to ensure the precision and efficiency. The yawing and pitching angular velocities are directly measured by gyros, while only the rolling angular velocity is inferred indirectly from the rolling angular information vector composed of rolling angular acceleration and quadratic component of rolling angular velocity. Based on the proposed scheme, the configuration ascertainment problem for acquiring the required installation parameters of accelerometers is transformed into a constraint optimization problem with the objective of minimizing the error of rolling angular information vector. A single channel rolling angular velocity calculation model is then established on the basis of the optimal configuration and the extended Kalman filter algorithm is utilized for state estimation. Simulations are implemented and results indicate that the optimal 5A2G scheme is feasible for high-speed rotating ammunition.

“…As a result, using only accelerometers in 3D angular motion measurement has a promising market. In early 1960s, some scholars presented to use accelerometers to measure rotational motion of a rigid object [3][4][5] , and from then on, people started to study rotary motion measured by the accelerometers and the theory of gyroscope-free strap-down inertial navigation system is greatly improved [6][7][8][9][10][11] . However, taking into account the particularity of mouse motion, the low frequency of user's wrist motion and weak acceleration data (about the tenth of gravity acceleration), in this paper a novel rotation angular model, by use of the static and tilting property of accelerometer [12] , is proposed to accurately identify the rotation angular motion and to be effectively applied in the 3D mouse system.…”

A new scheme is proposed to model 3D angular motion of a revolving regular object with miniature, low-cost micro electro mechanical systems (MEMS) accelerometers (instead of gyroscope), which is employed in 3D mouse system. To sense 3D angular motion, the static property of MEMS accelerometer, sensitive to gravity acceleration, is exploited. With the three outputs of configured accelerometers, the proposed model is implemented to get the rotary motion of the rigid object. In order to validate the effectiveness of the proposed model, an input device is developed with the configuration of the scheme. Experimental results show that a simulated 3D cube can accurately track the rotation of the input device. The result indicates the feasibility and effectiveness of the proposed model in the 3D mouse system.
