Abstract

The embodiment of the invention discloses a cooperative positioning method and system based on balance factor weighted iteration and a storage medium. The method comprises the steps that a positioningsolution model is constructed based on acquired satellite information and cooperative node information; according to the ranging variance of cooperative ranging and satellite ranging, local weight iscalculated; the global weight corresponding to the local weight is calculated based on a balance factor; the location information of a cooperative node is solved by combining the global weight and the positioning solution model; and the location information is sent to other cooperative nodes. According to the invention, the problem of difficult weight selection in cooperative positioning can be solved by through weight balancing.

Description

technical field [0001] The present invention relates to the technical field of co-location, in particular to a co-location method, system and storage medium based on balance factor weighted iteration. Background technique [0002] Location awareness is becoming more and more important in many applications. Such as unmanned systems, Internet of Things (IoT), and location-based services (LBS), the demand for high-precision and high-reliability locations is becoming more and more urgent. As the most widely used means of navigation and positioning at this stage, the global satellite navigation system plays a vital role in many industries. However, with the emergence of new technologies and new applications, the needs of navigation and positioning are becoming more and more diverse, and the scenarios are becoming more and more complex. The limitations of satellite positioning systems are gradually exposed. In some environments with poor line-of-sight conditions, such as indoors...
