Safe operation control in non-guided traffic requires high accuracy and availability of vehicle
localisation technology. Normally these requirements for vehicle localisation systems can
only be met by complex multi-sensor systems. Satellite-based localisation technology has in
recent times been increasingly used in traffic applications. However, satellite-based
localisation requires the reception of signals from at least four satellites. But on many tracks,
this visibility prerequisite cannot be fulfilled because of shadowing effects from the natural
environment, buildings etc. This results in a considerable loss of localisation availability.
At the Technical University of Braunschweig therefore a method and a test bed has been
developed within the "SATNAB" project, which allows the measurement of the accuracy and
availability of satellite positioning receivers.
This paper gives an overview of the used methodologies in order to analyse satellite
navigation systems in general and satellite-based vehicle localisation systems in detail. The
structure of the used mobile test bed in form of a measurement vehicle is presented in details.
The build up equipment allows qualifying single satellite receivers up to complete vehicle
