HIGH-ACCESSITY MOBILE NAVIGATION TERMINAL FOR MOBILE OBJECTS ON THE GROUND

Abstract

This utility model relates to navigation technology, satellite and inertial instrumentation, computing systems, and secure data transmission, and can be used in vehicles, robotic systems, geodetic systems, mobile object monitoring systems, and other technical equipment requiring high-precision determination of location coordinates, speed, and spatial orientation angles in real time and post-processing mode. The objective of this utility model is to create a high-precision mobile navigation terminal for ground-based mobile objects, providing automatic determination of location coordinates, speed, and spatial orientation angles in real time and post-processing mode, including in the presence of GNSS signal availability limitations, short-term signal loss, attenuation, or interference.The solution is aimed at improving the accuracy, continuity, and reliability of positioning, ensuring secure transmission of navigation data over open communication channels, and automatically identifying and displaying a moving object against an electronic map in monitoring and dispatching systems. The technical result of the proposed solution is a comprehensive increase in the efficiency and reliability of the navigation terminal through the combined processing of satellite and inertial data, ensuring high-precision positioning in real time and post-processing mode, continuously determining coordinates, velocity, and attitude angles during degraded GNSS signals, improving trajectory accuracy using correction information, secure transmission of navigation and service data, and expanding the terminal's functionality.In order to achieve the technical result, a high-precision mobile navigation terminal for ground-based mobile objects, including a GNSS antenna, a GNSS receiving module, a computing module, a communication module, a memory module, a power supply unit and a display means, according to the utility model, is additionally equipped with an inertial measurement module, a cryptographic module, an automatic object identification module and a module for generating a combined navigation solution, configured with the capability of jointly processing satellite and inertial measurements, assessing the quality of navigation data, recording raw GNSS observations and inertial measurement module data in memory, automatically switching between the satellite positioning mode, the combined GNSS / INS mode and the subsequent post-processing mode, as well as with the capability of encrypting and transmitting information via open communication channels and displaying the current or updated position of the object against the background of an electronic map.
