Abstract

The present invention provides a method for evaluating the credibility of mutual aided navigation and positioning data, comprising: receiving several mutual aided navigation and positioning data sent by several assistance terminals at the same time; for any mutual aided navigation and positioning data sent by any aid terminal, calculating the respective The credibility of the data source corresponding to the mutual-aided navigation and positioning data and the credibility of the data itself; based on the credibility of the data source and the credibility of the data itself, the received mutual-aided navigation and positioning data Do a joint evaluation. A method and system for evaluating the credibility of mutual assistance navigation and positioning data provided by the present invention evaluates by using the credibility of the assistance terminal data, the credibility of the intermediate transmission node, the data support relationship, and the data conflict relationship, without relying on prior knowledge or The credibility of pre-sequence data and subsequent data can adapt to the continuous change of mutual assistance navigation application scenarios.

Description

technical field [0001] The field of navigation and positioning data processing of the present invention, more specifically, relates to a method and system for evaluating the credibility of mutual assistance navigation and positioning data. Background technique [0002] There is a huge demand for spatio-temporal information. At present, with the rapid development of satellite navigation, wireless communication and other technologies, the promotion and popularization of various positioning terminals and communication terminals, and the continuous improvement of network infrastructure, mutual aid navigation and positioning has been applied. Mutual assistance in navigation and positioning refers to a party with navigation and positioning information, such as individuals, terminal devices, network servers, etc. sharing or sending navigation and positioning information to others or systems. Other people or systems are called recipients, enabling recipients to carry out subsequent...
