  1. 6. Terrain navigation for underwater vehicles

    Författare :Ingemar Nygren; Magnus Jansson; Stephen Rock; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : In this thesis a terrain positioning method for underwater vehicles called the correlation method is presented. Using the method the vehicle can determine its absolute position with the help of a sonar and a map of the bottom topography. LÄS MER

  3. 7. GNSS-aided INS for land vehicle positioning and navigation

    Författare :Isaac Skog; Peter Händel; Bengt Boberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : This thesis begins with a survey of current state-of-the art in-car navigation systems. The pros and cons of the four commonly used information sources — GNSS/RF-based positioning, vehicle motion sensors, vehicle models and map information — are described. Common filters to combine the information from the various sources are discussed. LÄS MER

  4. 8. Low-Cost Navigation Systems : A Study of Four Problems

    Författare :Isaac Skog; Peter Händel; Fredrik Gustafsson; KTH; []

    Sammanfattning : The recent advancements in wireless technology and the developmentof efficient spectrum sharing strategies have had a great impacton today's communication systems. It is not uncommon that severalnetworks are deployed in the same area, each serving multipleusers who expect ubiquitous access to various voice andinformation services. LÄS MER

  7. 10. On Reduced Rank Linear Regression and Direction Estimation in Unknown Colored Noise Fields

    Författare :Karl Werner; Magnus Jansson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; Signalbehandling;

    Sammanfattning : Two estimation problems are treated in this thesis. Estimators are suggested and the asymptotical properties of the estimates are investigated analytically. Numerical simulations are used to assess small-sample performance. In addition, performance bounds are calculated. LÄS MER
