Summary:This paper presents the preliminary results of a field experiment for low-cost strap down IMU/GPS combination for the estimation of 2-D components of vehicle position (Trajectory). In present approach the effects of earth rotation due to the low sensitivities of the sensors and gravity variations have been neglected. The scope of the experiment was to test the feasibility of IMU/GPS for a small AUV and to develop a procedure for their test and evaluation before integrating them in the final system
