    • Elevation Angle Redundancy from Barometric Altitude in Multipath-affected Phased Array Radio Navigation of UAVs 

      Okuhara, Mika; Bryne, Torleiv Håland; Gryte, Kristoffer; Johansen, Tor Arne (Journal article; Peer reviewed, 2024)
      Phased Array Radio Systems (PARS) are a promising alternative or backup to Global Navigation Satellite Systems (GNSS) based positioning, offering higher signal-to-noise ratio (SNR), narrow beam communication and robust ...

    • Phased Array Radio Navigation System on UAVs: GNSS-based Calibration in the Field 

      Okuhara, Mika; Bryne, Torleiv Håland; Gryte, Kristoffer; Johansen, Tor Arne (Peer reviewed; Journal article, 2021)
      With global coverage, high accuracy, and lightweight receivers, global navigation satellite system (GNSS) has been the major positioning solution for unmanned aerial vehicles (UAV). However, GNSS is prone to electromagnetic ...

    • Phased Array Radio Navigation System on UAVs: In-flight Calibration 

      Okuhara, Mika; Bryne, Torleiv Håland; Gryte, Kristoffer; Johansen, Tor Arne (Peer reviewed; Journal article, 2022)
      Global Navigation Satellite Systems (GNSS) has been the primary positioning solution for Unmanned Aerial Vehicles (UAVs) due to their worldwide coverage, high precision and lightweight receivers. However, GNSS is prone to ...

    • Phased Array Radio Navigation System on UAVs: Real-Time Implementation of In-flight Calibration 

      Okuhara, Mika; Bryne, Torleiv Håland; Gryte, Kristoffer; Johansen, Tor Arne (Peer reviewed; Journal article, 2023)
      Unmanned aerial vehicles (UAV) require an alternative positioning system to the global navigation satellite systems (GNSS) for safety-critical operations since GNSS is prone to unintentional or malicious electromagnetic ...

    • Phased Array Radio System Navigation of Unmanned Aerial Vehicles 

      Okuhara, Mika (Doctoral theses at NTNU;2024:265, Doctoral thesis, 2024)
      While global navigation satellite system (GNSS) provides accurate positioning and wide coverage for unmanned aerial vehicle (UAV) navigation, it is prone to threats like jamming and spoofing because of weak signal strength. ...
