From autonomous vehicles to connected wearable devices, accurate positioning information is required for all the Location-Based Services (LBS). For the safety-critical applications, however, the reliability of the positioning information is more important. If one can monitor the reliability of the information provided by the positioning system, in case of non-reliable positioning delivered, an alert can be sent to warn the users of the potential dangers. This is the concept of positioning integrity monitoring, which can guarantee the safety of the LBS users. As a hot issue originally introduced in the aviation domain for the Safety-of-Life (SoF) applications, positioning integrity monitoring has been being discussed and designed in recent years for terrestrial applications such as autonomous vehicles. For the wearable positioning systems, it is also important to know the uncertainty of the information provided by the whole system especially for reliability-critical applications such as guidance for blind people.
In this special session, we solicit novel papers related (but not limited to):

  • GNSS Positioning integrity monitoring for high accurate terrestrial applications
  • Integrity monitoring for PPP
  • Multisensor positioning integrity monitoring
  • Positioning uncertainty estimation
  • Measurement Fault Detection and Exclusion (FDE) techniques
  • AI techniques for Fault Detection and Exclusion (FDE)
