A study on volunteer augmentation navigation technology

Abstract

Navigation augmentation technology is one of the most common methods to increase the continuity, reliability and integrity of the global satellite navigation system. The concept of volunteer augmentation navigation (VNA) is proposed and the elements and topological structure of VNA are also analyzed in this paper. The study focuses on the neural network model that volunteers and ordinary users use modern communication information network to exchange self-organizing information. The neural cell model of Volunteer Augmentation Navigation using shared information is built. Thus interactive general relative positioning is realized. Then basic theories and methods of volunteer augmentation navigation are formed on the basis of the above-mentioned study. This study of realization mechanism of volunteer augmentation technology helps to form a relatively integral architecture of volunteer augmentation navigation. A user self-service satellite navigation augmentation which combines information exchange and navigation services may strengthen the continuity, reliability and integrity of the navigation system. The volunteer augmentation navigation theory proposed in this paper improves the traditional satellite navigation application model and expands the connotation and denotation of satellite navigation augmentation methods.
