  1. 1. Testing for verification and validation of an onboard orbit determination system exploiting GNSS : A nanosatellite application for HERMES-SP

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

    Author : Clara Nermark; [2023]
    Keywords : Onboard orbit determination system; GNSS; nanosatellite; testing; verification and validation; Ombord banbestämning; GNSS; nanosatellit; testning; verifikation och validering;

    Abstract : When developing products for space, including nanosatellites, the verification and validation process is a mandatory part of any project conducted within the European space industry. Within such a process, testing is a method for verification and validation. READ MORE

  3. 2. On-board processing with AI for more autonomous and capable satellite systems

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Tamina Lund; [2022]
    Keywords : Satellite telemetry forecasting; battery degradation prediction; LSTM; artificial intelligence; on-board processing;

    Abstract : While the use of Artificial Intelligence (AI) has faced a sharp up-rise in popularity in ground-based industries, such as for autonomous navigation in the automotive industry and predictive maintenance in manufacturing processes, it is yet only rarely used in space industry. Hence, this thesis aims to investigate the possibilities of using AI for processing on-board Earth-orbiting satellites while in orbit. READ MORE

  4. 3. Navigation Strategies for Improved Positioning of Autonomous Vehicles

    University essay from Linköpings universitet/Reglerteknik

    Author : David Sandmark; [2019]
    Keywords : MPC; positioning; nonlinear; linear; approximation; error; navigation; control; improved; covariance;

    Abstract : This report proposes three algorithms using model predictive control (MPC) in order to improve the positioning accuracy of an unmanned vehicle. The developed algorithms succeed in reducing the uncertainty in position by allowing the vehicle to deviate from a planned path, and can also handle the presence of occluding objects. READ MORE

  5. 4. A Kalman filter approach to reduce position error for pedestrian applications in areas of bad GPS reception

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Mattias Eliasson; [2014]
    Keywords : ;

    Abstract : The number of GPS-enabled devices are growing rapidly. A large segment of the growth is coupled to the growth of smartphones. Some location-based applications are relatively simple, requiring only a rough position estimate. READ MORE
