AI Technical Summary
Technical Problem
Existing navigation systems are difficult to achieve accurate navigation when GPS signals are not available or map information is incomplete, especially in environments with poor visibility.
Method used
Using a PRS channel based on the 5GNR system, a PRS positioning set is formed through the PRS channels of multiple base stations and multiplexed into a PRS navigation set. The user terminal judges the travel direction and plans the navigation path by measuring the PRS signal strength and arrival angle.
Benefits of technology
It realizes accurate navigation and path planning without GPS and map information, ensuring the accuracy and real-time navigation, and is suitable for outdoor and poor visibility environments.

Abstract
The present invention proposes a navigation system based on the PRS channel under the 5GNR system, which belongs to the field of 5GNR communication and navigation. A navigation system based on the PRS channel under the 5GNR system includes multiple base stations serving user terminals, each base station has its own PRS channel opened, the PRS channels of multiple base stations form a PRS positioning set, and the PRS positioning set is reused as a PRS navigation set, and each base station is configured with its own PRS signal pattern; when the user terminal needs to navigate, the base station obtains the user's position through the positioning function of the PRS channel, and plans the navigation path through the PRS navigation set, and the user terminal determines whether it is walking on the navigation path by measuring the PRS signal changes of the base station on the navigation path. Solve the problem of inaccurate navigation of the user terminal when it cannot obtain map information, environmental information and GPS navigation information, and at the same time, because the navigation information is simplified and formalized, it is also convenient to implement unmanned navigation.
