Problems solved by technology

[0002] The inability to obtain the location of a terminal (such as a mobile phone) will affect the provision of various location-based services, such as map navigation services, online car-hailing services, etc.
Existing terminals generally support satellite positioning, and satellite positioning often encounters the problem of satellite signals being interfered or blocked, which will cause the terminal to be unable to continuously and stably receive better quality positioning satellite signals, resulting in the inability to The TOW (Second time of Week, second in a week) representing the launch time of the satellite signal is calculated from the positioning satellite signal, and the existing satellite positioning position calculation scheme needs to solve the TOW of at least 4 satellites to complete the position calculation. This disclosure The inventor found that how to perform effective satellite positioning position calculation is one of the current technical problems to be solved in this field when the effective TOW cannot be calculated

Abstract

The embodiment of the invention discloses a positioning method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring code phase measurement data of at least five satellites received by a terminal; acquiring a rough positioning position, rough time and terminal equipment time of the terminal and ephemeris of the at least five satellites; based on the rough positioning position, the rough time and the terminal equipment time of the terminal, and the code phase measurement data and ephemeris of the at least five satellites, correcting the rough positioning position, the rough time and the terminal equipment time of the terminal until a correction item is smaller than or equal to a preset first threshold value; and determining the rough positioning position corrected by using the correction item as the GNSS positioning position of the terminal. According to the scheme, the GNSS positioning position of the terminal can be determined under the condition that a complete pseudo-range is not calculated in an environment that a satellite signal is weak or shielded, the requirement on time precision can be reduced, and the position calculation efficiency and accuracy are improved.
