Developments in Satellite and UAV Systems

The field of satellite and UAV systems is rapidly advancing with a focus on improving navigation, communication, and collision avoidance. Researchers are exploring innovative approaches, such as leveraging the differential flatness of UAV dynamics and utilizing reconfigurable intelligent surfaces to enhance navigation and communication services in urban canyons and indoor environments. Noteworthy papers include:

  • Flatness-based Finite-Horizon Multi-UAV Formation Trajectory Planning and Directionally Aware Collision Avoidance Tracking, which presents a novel collision-free finite-time formation control scheme for multiple UAVs.
  • Statistical Modeling for Accurate Characterization of Doppler Effect in LEO-Terrestrial Networks, which provides a generalized analytical framework for characterizing Doppler shifts in LEO systems.
  • ASTARS empowered Satellite Positioning Approach for Urban Canyons and Indoor Environments, which proposes a method for mitigating the loss of satellite navigation signals in urban canyons and indoor environments using active simultaneous transmitting and reflecting reconfigurable intelligent surfaces.
