Abstract

The embodiment of the invention provides a satellite positioning method and device, electronic equipment and a storage medium. The method comprises the steps of screening all available satellites at present according to a preset initial cut-off angle and the elevation angles of all the available satellites to obtain a first screening result, adjusting the initial cut-off angle according to the first screening result, screening all the current available satellites according to the adjusted cut-off angle to obtain a second screening result, and carrying out positioning calculation according to the second screening result. Therefore, poor positioning precision caused by large atmospheric error delay and a multipath effect due to an excessively low cut-off angle can be avoided, the situation in which the positioning precision is poor and even positioning cannot be carried out due to a small number of available satellites caused by an excessively high cut-off angle can be avoided, and the positioning precision is improved.

Description

technical field [0001] The present application relates to satellite positioning, in particular to a satellite positioning method, device, electronic equipment and storage medium. Background technique [0002] Global Navigation Satellite System (GNSS) can provide positioning, navigation and timing information quickly, accurately and all-weather, and has been widely used in recent years. [0003] Due to the large atmospheric delay error and the multipath effect of the low-elevation satellite, the positioning error is relatively large. In the existing GNSS positioning algorithm, a fixed cut-off angle (usually about 10°) is generally set to ensure that satellites with an elevation angle below the set fixed cut-off angle do not participate in the positioning calculation, thereby ensuring that the positioning accuracy is not affected by false Influence of low-elevation satellites with poor quality distance observations. [0004] However, when the above method is used for positio...
