  1. 21. Simulation of Precise Automatic Radio Frequency GroundStation Tracking For S-Band Satellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Akila Wajirakumara; [2021]
    Nyckelord :;

    Sammanfattning : Satellites are often known for possessing invariable motion causing its apparent position to drift in the sky from the perspective of a ground station. If these irregular drifts are not compensated, the performance of the communication link would be greatly affected. Hence, the satellite motion has to be tracked by the ground station antenna.

  5. 24. Airborne Angle-Only Geolocalization

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Tove Kallin; [2021]
    Nyckelord :Angle-only; Bearing-only; Bearing; Geolocalization; Localization; Jammers; NLS; EKF; UKF; Cramér-Rao Lower Bound; Terrain; Elevation Data;

    Sammanfattning : Airborne angle-only geolocalization is the localization of objects on ground level from airborne vehicles (AV) using bearing measurements, namely azimuth and elevation. This thesis aims to introduce elevation data of the terrain to the airborne angle-only geolocalization problem and to demonstrate that it could be applicable for localization of jammers. LÄS MER

  7. 25. Dual Polarized Geodesic Lens

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Freysteinn Vidar Vidarsson; [2020]
    Nyckelord :;

    Sammanfattning : Gradient-index (GRIN) lens antennas, such as the Luneburg lens, posses attractive electromagnetic properties. The smooth change in refractive index ensures no internal reflections and the focusing of the electromagnetic waves results in a directive antenna. The main challenge of the design of a GRIN lens is acquiring the required refractive index. LÄS MER
