Modern navigation systems require reliable information about the vehicle position not only on plain. Roads possibly lying on top of each other, can be found in large cities. For this, it is necessary to know the transition from a road level to another one. GPS (Global Positioning System) is not providing sufficiently accurate position information in these areas, because the received signals are disturbed. Therefore, inertial sensors can be employed. A linear state space observer is resented, which provides the road gradient. The covered height is obtained by multiplying the covered distance and the road gradient. Simulations and tests of the observer have shown, that reasonable results can be achieved.
