A positioning method includes: receiving detection data sent by a positioning device, in which the detection data includes first satellite data of multiple satellites; determining prediction noise of each satellite based on the first satellite data, and determining a weight of each satellite based on the prediction noise; and determining a position of the positioning device based on the weight and observation equations.

Positioning methods and cloud device

The present disclosure discloses a navigation method, a device, and a medium. The method includes: planning candidate routes based on a start position and an end position of a user, and obtaining a sequence of candidate road sections in each candidate route; matching each candidate road section in the sequence of candidate road sections in each candidate route with an association relationship between an actual road section and actual road auxiliary information, to obtain a sequence of auxiliary information of each candidate route; and sorting the auxiliary information in the sequence of auxiliary information of each candidate route to obtain a sorted result corresponding each candidate route, and selecting target road auxiliary information from the sequence of auxiliary information of each candidate route based on the sorted result, so as to select a target route from the candidate routes based on the target road auxiliary information.

Navigation method and apparatus based on electronic map, device and medium

The present application discloses a terminal device locating method, a terminal device, a system, an emergency locating server, an electronic device and a storage medium, and relates to locating and information flow technologies. A specific implementation solution is: acquiring dialing information of a call of a terminal device, sending information related to a location of the terminal device through a non-network channel to an emergency locating server if the call is determined to be an emergency call according to the dialing information, where the information related to the location of the terminal device is used to locate the terminal device and obtain locating information of the terminal device.
