摘要

The paper solves a problem of the estimation of the movingrnvehicle position. The position is measured by globalrnposition system (GPS) but outages sometimes occur in thernmeasurements. During these outages, the actual position isrnestimated using data from vehicle sensors. A moving vehiclernis described by a discrete-time state-space model withrnbounded noise. This model is constructed using kinematicsrnlaws and it can be used for arbitrary type of ground vehicle.rnBayesian approach is applied to obtain position estimates.rnThe maximum a posteriori (MAP) estimation converts tornthe nonlinear programming. The paper also discusses a settingrnof initial conditions for successful running of estimationrnprocess.
