  1. 1. Robust Aircraft Positioning using Signals of Opportunity with Direction of Arrival

    University essay from Linköpings universitet/Reglerteknik

    Author : Erik Axelsson; Sebastian Fagerstedt; [2023]
    Keywords : Simultaneous localisation and mapping; direction of arrival; signals of opportunity; extended Kalman filter; positioning;

    Abstract : This thesis considers the problem of using signals of opportunity (SOO) with known direction of arrival (DOA) for aircraft positioning. SOO is a collective name for a wide range of signals not intended for navigation but which can be intercepted by the radar warning system on an aircraft. READ MORE

  3. 2. A Quantitative Framework for Constructing a Multi-Asset CTA with a Momentum-Based Approach

    University essay from Uppsala universitet/Datalogi

    Author : Rebecca Fällström; [2023]
    Keywords : Commodity trading advisors; CTA; trend-following; momentum strategies; risk parity; equally weighted; Markowitz weights; optimization;

    Abstract : Commodity Trading Advisors (CTAs) have gained popularity due to their abilities to generate an absolute return strategy. Little is known about how CTAs work and what variables are important to tune in order to create a profitable strategy. READ MORE
