A Generalized TDoA/ToA Model for ToF Positioning [article]

Maximilian von Tschirschnitz, Marcel Wagner, Marc-Oliver Pahl and Georg Carle
2019 arXiv   pre-print
Many applications require positioning. Time of Flight (ToF) methods calculate distances by measuring the propagation time of signals. We present a novel ToF localization method.  ...  A major advantage of our approach is that it provides a comparable or better clock error robustness, i.e. the typical errors of crystal oscillators have negligible impact for TDoA and ToA measurements.  ...  Our ToF positioning is therefore suitable for applications such as swarm drone coordination, Indoor Navigation/Guidance, and autonomous driving.  ...
