A Bayesian Approach to Terrain-Aided Navigation

A Bayesian Approach to Terrain-aided Navigation

Terrain aided aircraft navigation can be used to detect and correct errors in inertial navigation systems The idea of terrain aided naviga tion is to measure the vertical distance to the ground and compare it with a map on board the aircraft The comparison between the mea surements and the map can be made in a number of ways Both batch and recursive algorithms have been applied to this problem ...

A Bayesian Approach to Terrain Aided Navigation II

The terrain aided navigation problem is a highly nonlinear estimation problem with application to aircraft navigation and missile guidance In this work the Bayesian approach is used to estimate the aircraft position With a quantization of the state space an implementable algorithm is found Problems with low excitation rough terrain and parallel position hypothesis are handled in a reliable way ...

Terrain Aided Underwater Navigation using Bayesian Statistics

Terrain aided navigation

In many autonomous underwater vehicle (AUV) applications, a basic problem is to determine the AUV's position accurately. Terrain aided navigation, which supports the existing inertial navigation system with terrain information, is a promising method. In this thesis, the Kalman filter and the Bayesian approach implemented as point mass filter are used in terrain aided navigation. To formulate a ...
