“…Recently, it was proposed to incorporate angular rate measurements in one of the three channels in order to get fast convergence (Acharya et al, 2011;Xiong et al, 2014). The measurement equations are derived in body frame (Acharya et al, 2011) and navigation frame (Xiong et al, 2014) respectively.…”

“…The measurement equations are derived in body frame (Acharya et al, 2011) and navigation frame (Xiong et al, 2014) respectively. Note that it is much similar to the velocity plus rate matching method in the transfer alignment (Rogers, 1991;B.…”

“…The information includes the local gravity (vertical) and angular velocity of the Earth's rotation. The Kalman filter and other digital filters are often adopted to decrease the interference to the measured value (Siddiqui, 2013;Acharya et al, 2009;Acharya et al, 2011). As additional instrumentation is not necessary, it is easy to operate.…”

AbstractPurpose -The purpose of this paper is to increase the measurement accuracy of assembly deviations of an inertial navigation system, a new evaluation and optimal method of assembly metrology system is proposed, which takes into account the uncertainty from laser tracker hardware and coordinate system transformation, and is based on the Monte Carlo method. Design/methodology/approach -The uncertainty model of the laser tracker is established and its parameters are obtained from the known repeated test data by kriging interpolation and the least squares method. The errors of coordinate transformation are reduced by using a weighted point matching method, and the uncertainty of the transformation parameters is obtained based on the generalized inverse theory. The weighting coefficients of each reference point are optimized by the particle swarm optimization method according to the assembly requirements. Findings -The experiment results show that measurement error and predicted results match well, and the assembly deviation uncertainty of large component is reduced by about 10 per cent compared with the singular value decomposition method. Originality/value -This paper proposes a method to evaluate and eliminate the influence of random errors of the laser tracker during evaluation process of coordinate translation parameters and assembly deviations. The proposed method would be useful to improve the assembly measurement accuracy through less measurement times.

“…For instance, Sahawneh [3], Arunasish [4] et al employ measures such as Kalman filtering technique and GPS/INS integrated navigation technology to ensure the accuracy and stability of the performance parameters of the inertial platform system. Sun [5], Liang [6] et al take measures such as temperature compensation and precise temperature control to ensure the stability of the heading sensitive drift.…”

For the missile inertial platform system with the characteristic of long-term storage and onetime use, temperature is a key factor that affects the long-term storage behavior of the heading sensitive drift, which is a major parameter of the missile inertial platform system. Based on the gyro's movement principle in the coordinate system of inertial platform system, the principle and expression of the heading sensitive drift caused by storage temperature was derived in this paper. Then, the storage characteristics of various drift parameters in the expression under the long-term influence of temperature were thoroughly analyzed, and the storage behavioral model of the heading sensitive drift under the influence of storage temperature was obtained. Finally, the long-term drift feature, the acceleration feature and the storage stability of the heading sensitive drift based on behavioral model was analyzed with the actual storage profile. The results indicate that the heading sensitive drift features no acceleration with the current storage temperature profile, but the influence of long-term temperature is obvious, which provides a basis for reasoned resource allocation for the calibration and maintenance in inertial platform system.
