AI Technical Summary
Technical Problem
In non-terrestrial network communication systems, terminal equipment may be unable to obtain usable location information due to GNSS failure, thus affecting the normal operation of communication.
Method used
When GNSS fails, the terminal device obtains the first location information through the LEO positioning algorithm and the second location information by combining it with the location prediction algorithm. The target location information is obtained by weighted average fusion to improve positioning accuracy.
Benefits of technology
In the event of GNSS failure, the terminal equipment can obtain higher-precision location information to ensure normal communication and uplink synchronization.

Abstract
The application discloses a position determination method, a communication device, a communication system, a storage medium and a chip system, and belongs to the technical field of communication. The method comprises the following steps: in the case that GNSS is invalid, a terminal device determines first position information based on a LEO positioning algorithm, obtains second position information based on a position prediction algorithm, and then fuses the first position information and the second position information to obtain target position information. In the application, the positioning accuracy after fusion is higher than the positioning accuracy of the LEO positioning algorithm and the position prediction algorithm respectively. In this way, the terminal device can also obtain target position information with higher accuracy when GNSS is invalid, thereby helping the normal communication.
