This chapter presents the various positioning technologies used in pedestrian navigation. The basic principles as well as the main advantages and disadvantages of positioning methods in the context of urban mobility are discussed. The development of navigation systems has led to the establishment of digital navigation maps containing the network of different traffic routes. In the future, pedestrian navigation technology, both attractive and feared, will be accepted if legal and commercial regulations of use prioritize the protection of the private sphere, preserving individual and free mobility.
