  2. 1. Recursive Bayesian Estimation : Navigation and Tracking Applications

    Author : Niclas Bergman; Fredrik Gustafsson; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Target tracking; Autonomous aircraft navigation; Terrain navigation;

    Abstract : Recursive estimation deals with the problem of extracting information about parameters, or states, of a dynamical system in real time, given noisy measurements of the system output. Recursive estimation plays a central role in many applications of signal processing, system identification and automatic control. READ MORE

  4. 2. Estimation and Detection with Applications to Navigation

    Author : David Törnqvist; Fredrik Gustafsson; Hugh Durrant-Whyte; Linköpings universitet; []
    Keywords : Navigation; SLAM; Particle Filter; Estimation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The ability to navigate in an unknown environment is an enabler for truly utonomous systems. Such a system must be aware of its relative position to the surroundings using sensor measurements. It is instrumental that these measurements are monitored for disturbances and faults. READ MORE

  5. 3. Selected Aspects of Navigation and Path Planning in Unmanned Aircraft Systems

    Author : Mariusz Wzorek; Andrzej Szałas; Jacek Malec; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Path planning; motion planning; autonomous Unmanned Aircraft Systems UAS ; Hierarchical Concurrent State Machines HCSM ; UAV;

    Abstract : Unmanned aircraft systems (UASs) are an important future technology with early generations already being used in many areas of application encompassing both military and civilian domains. This thesis proposes a number of integration techniques for combining control-based navigation with more abstract path planning functionality for UASs. READ MORE

  6. 4. User Preferred Trajectories in Commercial Aircraft Operation: Design and Implementation

    Author : Hanyo Vera Anders; Arthur Rizzi; Tobias Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeronautics; air traffic management; aircraft operation; flygteknik; flygledning; Engineering mechanics; Teknisk mekanik;

    Abstract : This report describes how an aircraft creates and flies its User Preferred Trajectory from take-off to landing, based on the objectives and constraints the aircraft is subjected to from a technological and operational viewpoint. A basic description of commercial aircraft operation is given, with an emphasis on identifying the different stakeholders (Air Navigation Service Providers, Airline Operation Center, Pilot/Aircraft, Airport and Civil Aviation Authority).

  7. 5. Bayesian Inference in Terrain Navigation

    Author : Niclas Bergman; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Terrain navigation is a concept for autonomous aircraft navigation. If measurements of the terrain height over mean sea-level are collected along the aircraft flight path, an estimate of the aircraft position can be formed by matching these measurements with a digital reference terrain map. This matching is a recursive nonlinear estimation problem. READ MORE
