  1. 1. Assisted GNSS Positioning using State Space Corrections

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Oskar Philipsson; [2023]
    Keywords : positioning; GNSS; SSR; EKF; sensor fusion;

    Abstract : Classical GNSS based positioning has accuracy limitations due to many sources oferror. The error sources range from clock errors and orbit errors toerrors due to variations in atmospheric propagation delays. One way to improve GNSSpositioning is to generate real time corrections using a GNSS reference network. READ MORE

    Abstract : GNSS (Global Navigation Satellite System) är system som gör det möjligt för en mottagare att känna sin position. Det täcker över GPS (Global Positioning System), ett system som drivs av USA, Galileo (europeisk), Beidou (kinesiska) och andra.För närvarande, med en fristående GPS-mottagare, är noggrannheten på positionen runt 1m.

  4. 3. Development of Simulation Tool and New Tracking Algorithms for Radio Occultation Receivers

    University essay from Kommunikationssystem; Tekniska högskolan

    Author : Oskar Rönnberg Sjödin; David Ahlsin; [2011]
    Keywords : radio occultation; gnss; galileo; gps; simulation software;

    Abstract : When a radio signal traverses the atmosphere it will be delayed by not only thedistance between transmitter and receiver, but also the atmosphere. Given knowl-edge of the characteristics of the sent signal the effect of the atmosphere can beobtained from the received signal. This concept is called radio occultation. READ MORE
