Uncertainty Analysis of Inertial Instruments for its Integration with Satellite Navigation

The development of vehicle navigation systems with low cost and medium uncertainty is necessary in order to perform an effective road vehicle fleet analysis. This work is a part of a project centered on the development of an integrated inertial - satellite navigation system which estimates in a very accurate way the kinematic variables of a vehicle during a set of different testing scenarios, including the development of driving cycles. A study for the uncertainty of the inertial navigation system is shown. The results provide criteria for the selection of the components of the system, including requirements on the satellite systems.
