Shoes with GPS that don’t need satellites


Modern navigation systems are based on the orientation of the instruments in space by using information received from GPS or GLONASS satellites. One of the problems with such devices is that they can work not always and strongly depend on the mass conditions. But recently, Russian scientists from the Siberian Federal University (SFU), together with colleagues from the National research Tomsk Polytechnic University (TPU) has developed a technology that will be able to determine the coordinates of the user without data from the satellites.

Such sensors can be equipped with shoes or other clothing items. And the invention is a pedestrian navigation system, which can determine coordinates of the user even in a dense urban environment, the forests and underground. As told to the author of the development of candidate of technical Sciences, associate Professor of instrumentation and nanoelectronics of the Institute of engineering physics and Radioelectronics, Siberian Federal University Pavel Maryushkin,

“The system does not need the antenna, and hence determines the coordinates of the location where it is impossible to use a satellite system such as GLONASS or GPS. The system itself is inertial, not dependent on external reference points or signals. The sensors detect the path by measuring accelerations, which moves the pedestrian. Knowing the origin of a route, the system will determine the distance traveled and the location of the user based on sensor information.”

The instruments themselves are quite compact. The measuring unit can be worn on the arm bracelet, but it is best to place it in the sole of the Shoe. During a series of experiments, the scientists conducted measurements, and they found out that the error location is not exceeded 2.5%. New development can be used in the individual navigation equipment not only to create analogues of GPS, but also for spatial orientation of people with vision problems.
