Retrospective Gap Filling - the Easy-OBU Way.

Popis výsledku v původním jazyce

The goal of Easy-OBU is to provide position information with a quality that is comparable to that when navigation satellites are available under conditions when this is normally not possible (e.g., in tunnels). In addition, the system must be affordable,highly flexible and portable. The approach of Easy-OBU to address this is to use, in the absence of GNSS, data collected by inexpensive sensors installed on an OBU. These data are stored and analysed with an intelligent filtering approach (noncausal filtering ? NCF) to calculate highly accurate positioning information, while accepting the limitation that this information is only available after a sufficient number of navigation satellites is visible again. Due to the high computational requirements itwas decided to perform calculation in a backoffice environment which is linked to the OBU. This also helps to reduce the costs of the OBUs and makes the use of more OBUs, e.g., for car fleets, very efficient.
