Most of the positioning technologies for modern inertial navigation systems have been
available for the last 25 years that has focused on development of the Strap-down Inertial
Navigation Systems (SINS) because of its low cost.
This paper presents an intelligent navigator to overcome the limitations of existing SINS
algorithms. This algorithm is based on Artificial Neural Network (ANN).
Using window based weight updating strategy; the intelligent navigator was evaluated using
several SINS hypothetical field tests data and the results demonstrated superior performance to
traditional navigator in the position domain.
