Abstract :
In this paper, the performance of a Ring Laser Gyro based inertial navigation is studied. It is modeled by using two methods; in the dynamic modeling, some parameters such as scale factor and environmental sensitivity have been determined, whereas in the statistical model, the other parameters such as random drift have been computed. Also the performance of the system is evaluated for several inputs and the dither influences on Gyro´s output, locking effect, scale factor and drift errors are investigated.
