Design of a GNSS Augment,Monitoring and Evaluation System for Test Ranges

The concept of GNSS （Global Navigation Satellite System） augment,monitoring and evaluation system for test ranges is defined to meet the complicated requirements including assurance of the accuracy of GNSS observables and reliability,abnormity diagnosis and wireless signal monitoring at test ranges.Following analysis of the characteristics of different augment,monitoring and evaluation technologies,the paper proposes a technical approach that uses wide area differential augment and ground integrity channel based on monitor station networks to meet high accuracy measurement and reliability requirements,and uses vehicle-borne integrated navigation and interference monitoring systems to meet occurrent abnormity diagnosis and wireless signal monitoring requirements in different regions,taking a wide area reference station network as the backbone.Design of the system architecture is described.Analysis of real time operation mode and data processing flow is highlighted.The results provide useful reference for construction of the system in the near future.
