Abstract: PROBLEM TO BE SOLVED: To provide a small-sized navigation system for a vehicle, having flexibility at determination of the present position from the pervious position, which is high in accuracy and efficiency and advantageous in term of cost. SOLUTION: Inertial guid sensors 212-216 detect the movement of a vehicle by a non-inertial coordinates system to from the sensor signals corresponding thereto. A deformation unit 304 is connected, in order to receive the sensor signals formed by the inertial guide sensors and deforms the sensor signals to a dummy inertial coordinates system to form the first signal corresponding thereto. A logic unit 308 receives the first signal formed by the deformation unit 304, to convert the same to the estimate value of the position and azimuth of the vehicle. COPYRIGHT: (C)2001,JPO

TL;DR: In this paper, a new single-axis rotation modulation scheme is proposed, which can effectively eliminate the effects of gyro constant drift in all directions compared with the conventional singleaxis rotation method and non-rotation method,thus making an improvement in the accuracy of position and attitudes greatly.
Abstract: Using rotation to compensate gyro drift is an effective method to improve the accuracy of strapdown inertial navigation systems(SINS).The constant drift of gyros in the inertial measurement unit(IMU) is translated into periodic signals by the use of rotation and can be eliminated by integration operation.A new single-axis rotation modulation scheme is proposed firstly.Then the proposed scheme is derived and analyzed theoretically,and a simulation experiment is demonstrated.The simulation results show that the presented scheme can effectively eliminate the effects of gyro constant drift in all directions compared with the conventional single-axis rotation method and non-rotation method,thus making an improvement in the accuracy of position and attitudes greatly.
