Abstract
Describes the GPS/inertial navigation system (GPSI) integration potential of a low cost inertial measurement unit (IMU) consisting of micro-machined sensors and on board calibration. Two simulated case studies demonstrate the IMU's performance in both flight and automotive navigation. Both studies show that the IMU can be successfully integrated with Kalman filtering into a GPSI system. With complete loss of GPS signals, position accuracy is shown to be less than 10 meters, 2 distance root mean square (drms), after 30 seconds.

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.

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.

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.
