[Delineating four major aspects, the mandatory national standard for satellite navigation and positioning reference station networks is released] On November 10, reporters learned today that the State Administration for Market Regulation approved the release of the mandatory national standard "Satellite Navigation and Positioning Base Station Network Security Requirements". This standard was proposed and coordinated by the Ministry of Natural Resources, clarifying safety technical requirements from the entire chain of facilities, data, and services, and providing technical support for standardizing the construction, operation and management of base station networks in accordance with the law, and ensuring the security of national spatiotemporal benchmarks and surveying and mapping geographic information. The standard is based on the safety management of the entire process of base station network construction, operation and service, and its core content includes four aspects. The first is to clarify the identification rules and service classifications of benchmark station networks. Define the definition and technical identification characteristics of base stations and base station networks, and divide base station network services into two categories: surveying and mapping benchmark services and other social services, providing a unified basis for classified and hierarchical supervision. The second is to strengthen rigid management and control of facility safety. Unapproved base station facilities are not allowed to be set up in military restricted areas or military management areas; base stations are equipped with isolation and protection facilities, and hierarchical authority management is implemented for access and operation of site equipment; data processing, service and management systems must obtain a third-level filing certificate for network security level protection to build a strong defense line for facility security. The third is to strictly implement hierarchical management of data security. Base station network data shall be subject to hierarchical management and control of confidential data and important data according to the degree of data sensitivity; original observation data must be encrypted and transmitted through a dedicated wired network or commercial encryption technology, and important data services shall be subject to user real-name review and access control to prevent data leakage and tampering, and effectively safeguard national security. The fourth is to standardize the safe operation of services. Real-time services involving sensitive data must be equipped with security isolation and protective measures; the base station network that provides services to the society should be regularly traced to the national unified surveying and mapping benchmark to ensure service security and data credibility.
