Slip-Correction Methods for Improved Dead Reckoning in Autonomous Wheeled Robots
This work compares methods for improving the dead-reckoning capabilities of a mobile robot in the presence of longitudinal slip. They were evaluated using a standardized test of driving in a 140-centimetre square. Testing was conducted on high-friction rubber and low-friction artificial ice …

LSTM and extended dead reckoning automobile route prediction using smartphone sensors
… route taken. The two approaches, Extended Dead Reckoning and LSTM, are compared for their advantages and disadvantages. These concepts are explored by recording nearly one thousand miles of driving data from Virginia to Indiana to Illinois. The GPS data is used to train the LSTM neural …

Development of a Physics-Aware Dead Reckoning Mechanism for Distributed Interactive Applications
… scheme for shared objects, and a physics-aware dead reckoning model with an adaptive error threshold. The first part is intended to place a bound on the overall inconsistency present in shared objects, while the second is implemented to minimise the instantaneous inconsistency during users’ …

Enhancing Body-Mounted LiDAR SLAM using an IMU-based Pedestrian Dead Reckoning (PDR) Model
… an integrated sensor fusion scheme. A Pedestrian Dead Reckoning (PDR) model based on inertial sensors is used to enhance LiDAR-based SLAM. This proposed fusion uses the PDR model as a replacement for wheel odometry in vehicular platforms. A system prototype has been developed and used for data …

Dead reckoning : where we stand on privacy and security controls for the Internet of Things
This thesis provides an analysis of privacy and security controls for internet-connected data-driven systems, known as the Internet of Things (IoT). The grounding theory is that numerous pre-existing privacy and security control methods -- not necessarily crafted for IoT -- will bear on the future …

MEMS IMU navigation with model based dead-reckoning and one-way-travel-time acoustic range measurements for autonomous underwater vehicles
Recent advances in acoustic navigation methodologies are enabling the way for AUVs to extend their submerged mission time and maintain a bounded XY position error. Additionally, advances in inertial sensor technology have drastically lowered the size, power consumption, and cost of these sensors. …

A Localization Solution for an Autonomous Vehicle in an Urban Environment
… and can be solved sufficiently using simple dead reckoning or an off-the-shelf GPS with differential corrections. However, as the surroundings become more complex, so does the localization problem. The urban environment is a prime example of a situation in which a vehicle's surroundings …

Contributions to automated realtime underwater navigation
… are: i) in situ navigation sensor alignment, ii) dead reckoning through the water column, and iii) model-driven delayed measurement fusion. Contributions to each of these areas have been demonstrated in simulation, with laboratory data, or in the field–some have been demonstrated in all three …

Robot navigation using ultrasonic feedback
… and this information was combined with dead reckoning data to build a two-dimensional map of the environment. Borenstein's Histogramic In-Motion Mapping technique was used to build sensor maps, which were analyzed to find features such as walls and corners. The features were matched with …

Towards Autonomous Localization of an Underwater Drone
… successful localization and navigation: inertial/dead-reckoning, acoustic signals, and geophysical data. This thesis examines autonomous localization in a simulated environment for an OpenROV Underwater Drone using a Kalman Filter. This filter performs state estimation for a dead reckoning system …

Development and Implementation of a Self-Building Global Map for Autonomous Navigation
… known as odometry. Odometry, also referred to as dead reckoning, is subject to inaccuracy caused by systematic and non-systematic errors. In many cases, the most dominant source of inaccuracy is systematic errors. Systematic errors are inherent to the vehicle; therefore, the dead reckoning …

Localisation, tracking, and navigation support for pedestrians in uninstrumented and unknown environments
… and look for complementary oolutions. Pedestrian dead reckoning (PDR) based on foot-mounted inertial sensors is a promising method which we describe in detail, including its inherent flaws. We combine the dead reckoning and sensor node techniques to perform simultaneous localisation and mapping …

Maze Learning and Recall in Weakly Electric Fish, Mormyrus rume proboscirostris Boulenger 1898 (Teleostei, Mormyridae): Sensory Bases
… such path integration, landmark orientation, or dead reckoning is far from settled. Nocturnal weakly electric fish (family Mormyridae) leave their daytime hiding places at night to forage for food and return at dawn. Thus, these fish provide an excellent model to explore their navigational …

Multiple-vehicle resource-constrained navigation in the deep ocean
… as GPS is not available underwater and dead-reckoning based on inertial or bottom-lock methods can require expensive sensors and suffers from drift. Due to zero drift, acoustic navigation methods are attractive as replacements or supplements to dead-reckoning, and centralized systems …
