Dynamic attitude measurement method and apparatus
TL;DR: In this paper, the attitude of an accelerating object is estimated by measuring acceleration with accelerometers in three orthogonal axes and measuring angular rate with angular rate sensors disposed about each such axis to compute attitude of the object accurately relative to a vertical axis.
Journal ArticleDOI
A car test for the estimation of GPS/INS alignment errors
TL;DR: Car test results on the estimation of alignment errors in the integration of a low-grade inertial measurement unit (IMU) with accurate GPS measurement systems showed that changes in the angular velocity improve the estimationof the lever arm between the GPS antenna and IMU.
Journal ArticleDOI
Fault detection and isolation for on-board sensors of a general aviation aircraft
TL;DR: In this paper, a polynomial approach for the design of residual generators in order to realize complete diagnosis schemes when additive faults are present is proposed, which leads to dynamic filters that can achieve both good disturbance signal decoupling and robustness properties with respect to both linearization error and measurement noise.

Design and Analysis of a Fault-Tolerant Coplanar Gyro-Free Inertial Measurement Unit
TL;DR: In this paper, a fault-tolerant, coplanar, and gyro-free inertial measurement unit (IMU) is proposed to perform six degree-of-freedom measurements for an object in motion.

Inertial navigation technology from 1970-1995.
TL;DR: The period since 1970 has been characterized by an intense push to develop new inertial navigation technology as mentioned in this paper, and the trend to smaller, lighter, less-expensive systems is certain to continue well into the next century.
