Abstract: A positioning method and an on-board device. The method includes: acquiring positioning data of a vehicle from a satellite and positioning correction data from a base station; acquiring target positioning data of the vehicle by correcting the positioning data based on the positioning correction data; and sending the target positioning data to a terminal device to enable the terminal device to position the vehicle according to the target positioning data.

Abstract: An ephemeris data processing method, electronic device and storage medium are disclosed, which relate to the fields of satellite communication, positioning, and navigation. The ephemeris data processing method includes: receiving raw ephemeris data from a plurality of user devices; analyzing the raw ephemeris data according to an analysis mode of each user device and a satellite ephemeris protocol of each galaxy. According to embodiments of the present disclosure, ephemeris data of a plurality of user devices can be centrally processed and stored, thereby storing more complete ephemeris data and then providing more abundant ephemeris data.

Abstract: A method for guiding a blind, an electronic device, a storage medium and a blind guide product, and related to the technical field of navigation are provided. The method includes: acquiring Beidou satellite data and base station differential data, and determining location information of a user by using a carrier phase differential technology; in response to a blind guide request, generating a blind guide route according to current location information and destination information input by the user; and broadcasting a voice prompt based on the blind guide route. The location accuracy of a user is improved, and blind guide requirements for a complex road section can be met, thereby improving the travel safety for the user.
