High reliability local positioning navigation system

High reliability local positioning navigation system

Algorithmic and technological approaches to the technological-constructive and algorithmic-software integration of the complex of navigation-visual modules and sensors are determined. A patent information study was carried out on a number of technical and technological solutions. A physical and mathematical model for solving navigation problems with the structure of a local navigation positional system has been developed. Optimal design parameters and operating modes of robotic platforms for a local navigation system have been developed.
