Multi-sensor cooperative autonomous integrity monitoring for Intelligent Transport Systems

Abstract

The integrity of the positioning system solution can be defined as a measure of trust one can put in the value of the estimated position. Some authors have called it ``a guarantee of safety''. Due to the safety implications, the Global Navigation Satellite Systems (GNSS) position integrity monitoring was first used in civil aviation. Integrity has become a key performance metric for Intelligent Transport Systems (ITS) given the ongoing efforts to develop more robust integrity monitoring algorithms for land-based applications in GNSS-challenged environments. However, ``a guarantee of safety'' cannot be given without any risk of misleading information associated with it. This risk exists due..
