Fig. 3. Three navigation tracks from the ROV Jason, lowering #230. The "DVL" track shows the dead-reckoning resulting from the DVL odometry alone. The "Exact LBL" track shows the standalone LBL solution. The "EKF Estimate" track shows the combination of both the DVL and LBL information using an extended Kalman filter framework. All tracks are started at the "Origin". The tracklines were executed over 3.5 hours at an average depth of 2,265 m.
