    • A Review on Precise Orbit Determination of Various LEO Satellites 

      Selvan, Kannan; Siemuri, Akpo; Kuusniemi, Heidi; Välisuo, Petri; Ometov, Aleksandr; Nurmi, Jari; Lohan, Elena Simona; Torres-Sospedra, Joaquín; Kuusniemi, Heidi (CEUR, 11.06.2021)
      The need for precise orbit determination (POD) has grown significantly due to the increased amount of space-based activities appearing at an accelerating pace. POD has a positive contribution in achieving the requirements ...
    • Can You Trust Your Pose? Confidence Estimation in Visual Localization 

      Ferranti, Luca; Li, Xiaotian; Boutellier, Jani; Kannala, Juho (IEEE, 05.05.2021)
      Camera pose estimation in large-scale environments is still an open question and, despite recent promising results, it may still fail in some situations. The research so far has focused on improving subcomponents of ...
    • Comparison of Machine Learning algorithms for venue presence with inclusion of neighbours 

      Khan, Wiqar; Raza, Asif; Kuusniemi, Heidi; Elmusrati, Mohammed (IEEE, 29.12.2021)
      User presence determination for being inside a venue, such that the user is provided with possible value-added services, is of high significance. It will get more prominent as we move to 5G and 6G networks’ rollout as we’ll ...
    • Data protection and space : What challenges will the General Data Protection Regulation face when dealing with space-based data? 

      Bu-Pasha, Shakila; Kuusniemi, Heidi (Henry Stewart Publications, 01.01.2021)
      Recently, space or satellite technology, as well as space data applications, is developing rapidly, resulting in a variety of uses. At the same time, related legal issues raise questions about how they can be handled ...
    • Homotopy Continuation for Sensor Networks Self-Calibration 

      Ferranti, Luca; Åström, Kalle; Oskarsson, Magnus; Boutellier, Jani; Kannala, Juho (IEEEEuropean Association for Signal Processing (EURASIP), 08.12.2021)
      Given a sensor network, TDOA self-calibration aims at simultaneously estimating the positions of receivers and transmitters, and transmitters time offsets. This can be formulated as a system of polynomial equations. Due ...
    • Legal aspects, public interest, and legitimate interest in processing personal data to operate autonomous buses in the regular transportation system 

      Bu-Pasha, Shakila (Wiley, 21.06.2022)
      Autonomous or robot vehicles are manufactured with such advanced technologies that they are technically able to operate without human intervention. The number of sensors deployed in automated vehicles is increasing, which ...
    • Machine Learning Utilization in GNSS : Use Cases, Challenges and Future Applications 

      Siemuri, Akpojoto; Kuusniemi, Heidi; Elmusrati, Mohammed S.; Välisuo, Petri; Shamsuzzoha, Ahm (IEEE, 15.06.2021)
      The algorithms and models of traditional global navigation satellite systems (GNSSs) perform very well in terms of the availability and accuracy of positioning, navigation and timing (PNT) under good signal conditions. ...
