Abstract
AbstractSatellite-based navigation is a transformational technology that underpins almost all aspects of modern life. However, there are environments where global navigation satellite systems (GNSS) are not available, for example undersea or underground, and navigation that is robust to GNSS outages is also required for resilient systems. Here we explore the potential for quantum diamond magnetometers as aids to obtain external position fix for navigation in global navigation satellite systems (GNSS)-denied environments. Diamond magnetometers offer high sensitivity and low measurement noise. We demonstrate this by simulating external position fix from the magnetic field measurements with a geographical data map using the probabilistic multiple hypotheses map matching filter with probabilistic data association for data mapping.
