The present work consists of the investigation of the navigation of Pioneer 10 and 11 probes becoming known as the “Pioneer Anomaly”: the trajectories followed by the spacecrafts did not match the ones retrieved with standard navigation software. Mismatching appeared as a linear drift in the Doppler data received by the spacecrafts, which has been ascribed to a constant sunward acceleration of about 8.5×10-10 m/s2. The study presented hereafter tries to find a convincing explanation to this disc...

Le caractère essentiel de l'Agence pour la sécurité de la navigation aérienne en Afrique et à Madagascar, ASECNA, est la dualité de sa nature. C'est à la fois un instrument d'assistance technique et un organisme de coopération en matière de sécurité aérienne. Historiquement l’ASECNA est le résultat d'une déconcentration de l'administration française de l'aviation civile, le Secrétariat Général à l'Aviation Civile (1). Cette opération fut rendue nécessaire par la décolonisation effectuée par la F...

Automated Guided Vehicles (AGVs) depend on sensor systems to guide and navigate in manufacturing environments. The sensor system must ensure the correct path is followed and monitor the vehicle’s progress as it proceeds through the environment to complete assigned tasks. An AGV therefore needs an efficient guidance and navigation system, based on sensor technology that allows it to navigate safely and accurately. A variable sensor system will provide an AGV with the ability to interchange guid...

Steerable catheters are routinely deployed in the treatment of cardiac arrhythmias. During invasive electrophysiology studies, the catheter handle is manipulated by an interventionalist to guide the catheter's distal section toward endocardium for pacing and ablation. Catheter manipulation requires dexterity and experience, and exposes the interventionalist to ionizing radiation. Through the course of this research, a platform was developed to assist and enhance the navigation of the catheter in...

The purpose of the thesis was to explore the possibilities of using a Level-Set method to design a time-optimal path planar of a subject to direction-dependent maximum velocities. A promising application for such a planning approach lies in sailboat navigation planning, because of the dynamic ocean waves, current, wind and the characteristics of a sailboat. In the thesis, we developed an IOS application to simulate such scenario as environment properties with wind, static obstacles and the sailb...

We present two different methods based on visual odometry for pose estimation (x, y, Ө) of a robot. The methods proposed are: one appearance based method that computes similarity measures between consecutive images, and one method that computes visual flow of particular features, i.e. spotlights on ceiling. Both techniques are used to correct the pose (x, y, Ө) of the robot, measuring heading change between consecutive images. A simple Kalman filter, extended Kalman filter and simple averaging f...

We consider an abstract representation of some environment in which an agent is located. Given a goal sequence, we ask what strategy said agent - utilizing readily available algorithmic tools - should incorporate to successfully find a valid traversal route such that it is optimal in accordance with a predefined error-margin. We present four scenarios that each incorporate aspects common to general navigation to further illustrate some of the difficult problems needed to be solved in any general...

Revisiting a crime scene is a vital part of investigating a crime. When physically visiting a crime scene there is however always a risk of contaminating the scene, and when working on a cold case, chances are that the physical crime has been altered. This thesis aims to explore what tools a criminal investigator would need to investigate a crime in a virtual environment and if a virtual reconstruction of a crime scene can be used to aid investigators when solving crimes. To explore these questi...

In navigation from one place to another, spatial knowledge helps us establish a destination and route while travelling. Therefore, sufficient spatial knowledge is a vital element in successful navigation. To build adequate spatial knowledge, various forms of spatial tools have been introduced to deliver spatial information without direct experience (maps, descriptions, pictures, etc.). An innovation developed in the 1970s and available on many handheld platforms from the early 2000s is the Globa...

Navigation and guidance of mobile robots towards steady or maneuvering objects (targets) is one of the most important areas of robotics that has attracted a lot of attention in recent decades. However, in most of the existing methods, both the line-of-sight angle (bearing) and the relative distance (range) are assumed to be available for navigation and guidance algorithms. There is also a relatively large body of research on navigation and guidance with bearings-only measurements. In contrast, o...
