Abstract: Data obtained and preferably stored or buffered by the positioning system for racing cars according to an older, separate application PCT/EP00/10518 is used to support computer-based simulation games, The reference data obtained in such a way forms marginal conditions for the computer simulation game. The use of the positioning system, or the data obtained thereby, opens up the possibility of providing such simulation games with an as yet unachieved realistic touch. The real-time axis of the racing course, for example, or the real driving condition data and operating data pertained to the racing cars during the real finished or ongoing race are entered as marginal conditions for the simulation game. Tis data can be made compatible with the simulation immediately by means of appropriate interface software.
