A new satellite-independent pedestrian navigator is tested in Krasnoyarsk
Researchers from the Siberian Federal University (SFU) and Tomsk Polytechnic University (TPU) have created a compact navigation device with microelectromechanical elements. The device does`t need satellite signals and consumes little energy.
The navigator has several miniature microelectromechanical sensors – gyroscopes and accelerometers – allowing to measure the speed of movement and determine the position of a pedestrian. «The pedestrian navigation system is built on inertial principles, which ensures its universality, complete autonomy and noise immunity», told the SFU press service. This navigator can determine the position where the use of satellite navigation systems isn`t always possible. For example, in densely built-up and indoor environments.
The results of the study are published in the collection of research papers SIBCON-2017.
The shoe sole is the optimal point for the navigation system placing. Microelectromechanical sensors have made it possible to make the device compact and not demanding for energy sources. Results of the developed inertial pedestrian navigation system tests revealed that error can be lowered down to less than 2.5 % of the distance covered. In future, such devices may be used by the military, rescuers, firemen, geologists. Besides, inertial devices can become assistants in orientation for the blind.
