Abstract

The application belongs to the field of communication technology, and discloses a positioning method, device, electronic equipment and readable storage medium. The method includes acquiring position information of multiple grid points in a set area and corresponding current ionospheric delay information; Based on the position information of each grid point and the corresponding current ionospheric delay information, the ionospheric correction model is constructed; based on the obtained target object position information and the ionospheric correction model, the ionospheric delay correction information of the target object is obtained; according to the ionospheric Delay correction information to locate the target object and improve the positioning accuracy.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a positioning method, device, electronic equipment, and readable storage medium. Background technique [0002] Satellite navigation system is an important space information infrastructure. It has been widely used in many fields such as surveying and mapping, telecommunications, water conservancy, fishery, transportation, forest fire prevention, disaster reduction and relief, public safety and military affairs, and is closely related to national security. Take the BeiDou Navigation Satellite System (BDSBAS) as an example. The BeiDou Satellite Navigation System is an independently developed and independently operated global satellite navigation system being implemented by China. The system is committed to providing high-quality positioning, navigation and timing services to users around the world. [0003] Due to different latitudes and different geographical...
