  3. 2. The Effect of Distortions Induced by Adaptive Antenna Arrays in GNSS Applications

    University essay from Linköpings universitet/Kommunikationssystem; Linköpings universitet/Tekniska fakulteten

    Author : Emma Beskow; [2022]
    Keywords : GNSS; GPS; Jamming; Beamforming; Adaptive antenna arrays; Frequency response distortions;

    Abstract : Global Navigation Satellite Systems (GNSS) are vital tools for accurate navigation and timing for both civil and military use. Due to the low power of the GNSS signals, these systems are sensitive to interference attacks. For wideband GNSS jamming, adaptive antenna arrays are commonly used to suppress interference.

    Abstract : Time synchronization is critical for the operation of radio base stations (RBS) in telecommunication companies. Global navigation satellite system (GNSS) is an existing technology to provide precise timing information to distributed RBSs. READ MORE

  5. 4. Impact of Time Synchronization Accuracy in Integrated Navigation Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Hemanth Ram Kartik Bommakanti; [2019]
    Keywords : Real-Time Solution; Time Synchronization; Integrated Navigation System; Global Navigation Satellite System; Inertial Measurement Unit; Realtidslösning; tidssynkronisering; integrerat navigationssystem; globalt satellitbaserat navigationssystem; tröghetsmätningsenhet;

    Abstract : Global Navigation Satellite System/Inertial Measurement Unit (GNSS/IMU) Integrated Navigation Systems (INS) integrate the positive features of GNSS and IMU for optimal navigation guidance in high accuracy outdoor navigation systems, for example using Extended Kalman Filter (EKF) techniques. Time synchronization of IMU data with precise GNSS based time is necessary to accurately synchronize the two systems. READ MORE
