Due to errors in position deter­mi­na­tion as well as of the commu­ni­ca­tion via serial inter­faces a new version of the operating system COSPAS was to be developed for tramway appli­ca­tions. For this inter alia expert’s opinions and assess­ments had to be drawn up by GRABAND worldwide for the on­board and radio equipment ZUB (train control system) 222c and 242 of different types on the basis of CENELEC norms.
