Use of High Sensitivity GNSS Receiver Doppler Measurements for Indoor Pedestrian Dead Reckoning
Sensors, 2013 Dead-reckoning (DR) algorithms, which use self-contained inertial sensors combined with gait analysis, have proven to be effective for pedestrian navigation purposes. In such DR systems, the primary error is often due to accumulated heading drifts.

Correcting Inertial Dead Reckoning Location Using Collision Avoidance Velocity-Based Map Matching
Applied Sciences, 2018 We propose an algorithm for map-aided inertial dead reckoning (DR) for indoor navigation. The technique is based on a concept of collision avoidance velocity.

Dead Reckoning for Trajectory Estimation of Underwater Drifters under Water Currents †
Journal of Marine Science and Engineering, 2020 Between external position updates, the most useful technique for trajectory estimation of a submerged drifter is dead reckoning (DR). These devices drift with the water current to measure the current’s velocity or to observe physical phenomena.

Three-Dimensional Dead-Reckoning Based on Lie Theory for Overcoming Approximation Errors
Applied SciencesThis paper proposes a dead-reckoning (DR) method for vehicles using Lie theory. This approach treats the pose (position and attitude) and velocity of the vehicle as elements of the Lie group SE2(3) and follows the computations based on Lie theory ...

Visual Tracking in Unknown Environments Using Fuzzy Logic and Dead Reckoning
International Journal of Advanced Robotic Systems, 2016 This paper addresses the problem of making a non-holonomic wheeled mobile robot (WMR) move to a target object using computer vision and obstacle-avoidance techniques. If a priori information about the obstacles is available, pre-planning the desired path

Waypoint Transfer Module between Autonomous Driving Maps Based on LiDAR Directional Sub-Images [PDF]
SensorsLane graphs are very important for describing road semantics and enabling safe autonomous maneuvers using the localization and path-planning modules. These graphs are considered long-life details because of the rare changes occurring in road structures ...
