  1. 1. Optimisation Of Ionospheric Scintillation Model Used In Radio Occultation

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Marta Boryczko; Tomasz Dziendziel; [2016]
    Nyckelord :Global Positioning System; ionospheric scintillation; optimization; Radio Occultation;

    Sammanfattning : This thesis is executed in cooperation with RUAG Space AB, which specializes in highly reliable on-board satellite equipment. The thesis focuses on the effect, which disturbs the amplitude and phase of a Global Positioning System (GPS) signal, called scintillation effect. It has a substantial impact on a GPS signal, during Radio Occultation (RO). LÄS MER

  3. 2. Implementation of Full Spectrum Inversion Method to Retrieve Bending Angle based on Simulated Data

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Arkadiusz Lebkowski; Krzysztof Nadolny; [2013]
    Nyckelord :atmosphere; bending angle; Full Spectrum Inversion; GPS; LEO; radio occultation; satellites; weather forecasting;

    Sammanfattning : This master thesis was done in cooperation with RUAG Space AB. Currently RUAG is working on designing the next generation instrument using Radio Occultation (RO) for climate monitoring and atmospheric sounding. RO is a method used to measure the temperature, pressure and humidity of the Earth's atmosphere. LÄS MER

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

    Master-uppsats, Kommunikationssystem; Tekniska högskolan

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

    Sammanfattning : 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. LÄS MER
