Journal ArticleDOI
A new multi-position calibration method for MEMS inertial navigation systems
TL;DR: A new multi-position calibration method was designed for MEMS of high to medium quality that has been adapted to compensate for the primary sensor errors, including the important scale factor and non-orthogonality errors of the gyroscopes.
Journal ArticleDOI
A Standard Testing and Calibration Procedure for Low Cost MEMS Inertial Sensors and Units
TL;DR: In this paper, the Allan variance method is used to characterize the noise in the MEMS sensors and a six-position calibration method is applied to estimate the deterministic sensor errors such as bias, scale factor, and non-orthogonality.
Journal ArticleDOI
An Accurate Land-Vehicle MEMS IMU/GPS Navigation System Using 3D Auxiliary Velocity Updates
TL;DR: 3D Auxiliary Velocity Updates (AVUs) are used, namely, non-holonomic constraints and odometer-derived velocity and results showed a significant accuracy improvement after applying AVUs.
Journal ArticleDOI
Civilian Vehicle Navigation: Required Alignment of the Inertial Sensors for Acceptable Navigation Accuracies
TL;DR: The effects of misalignment errors that will produce errors in initial alignment and affect the navigation accuracy for two different inertial systems are investigated.
Journal ArticleDOI
A universal approach for processing any MEMS inertial sensor configuration for land-vehicle navigation
TL;DR: A universal approach for processing any MEMS sensor configuration for land vehicular navigation is introduced based on the assumption that the omitted sensors provide relatively less navigation information and hence, their output can be replaced by pseudo constant signals plus noise.
