The error analysis for transversal strapdown INS reveals the fact that errors of the navigation quantity would drift as time going on.
The average lateral error of the navigation system of the robots was less than 0.04 m, and the efficiency of the leader follower system was improved by 95.1% compared with that of a conventional single robot.
As forced high-power pulse interferences, DME signal will decrease SINR (signal-to-interference and noise ratio) at the receiver, reduce the acquisition satellite numbers, make the tracking loop unlocked, and finally lead to the decoding error or failure of navigation information [1 4].
This minor discrepancy might be ascribed to different factors: i) small co-registration errors, that clearly reduce the reproducibility of navigation; ii) small errors in re-positioning the EEG cap; iii) unavoidable and unpredictable biological variability due to changes in brain excitability that likely takes place on the time-scale of several days.
Those failures, though, include both the Mars lander and its companion craft, the $125 million Mars Climate Orbiter, which was lost on Sept. 23 because of navigation errors caused by the failure to convert English measurements to metric.
The criteria for driving performance were trip duration, driving speed and number of navigation errors.
The shape model does a much better job of accounting for this pattern of navigation errors, as can be seen in Fig. 7c and confirmed by the red triangles in Fig. 11.
Naturally, this location is the most likely one, as is confirmed by our modelling, but the distribution of navigation errors that participants make around this point and, in particular, the variation in this distribution with the location of the landmarks in the scene, is something we attempt to predict using a reconstruction model.
An image-aided inertial navigation system (IA-INS) implies that the errors of an inertial navigator are estimated via the Kalman filter using measurements derived from images.
