Sheives, T C; Andreas, R D

A new approach for applying SITAN (Sandia Inertial Terrain Aided Navigation) to applications involving large initial position errors is described and analyzed. The approach uses parallel Kalman filters in combination with a selection algorithm to estimate the errors in the reference navigation system. Monte Carlo simulation and covariance analysis results are presented which demonstrate the feasibility and practicality of the approach.
