Abstract
Metadata is of great significance to realizing fast sharing, distribution and service of big data of Beidou navigation and location service. In this paper, a general design framework is proposed for Beidou navigation and location service metadata registration management technology; The in-depth discussions are developed to the business requirements, business processes and computer technology involved in Beidou navigation and location service metadata registration management. Efficient management of massive Beidou navigation and location service big data can be implemented based on HDFS storage and Spark distributed parallel computing technology. HDFS can achieve distributed storage of data, in the big data environment, HDFS can ensure data consistency and data disaster recovery; Spark can realize data caching and reasonable and the efficient task scheduling as a distributed parallel computing framework, which provides a foundation for efficient query of Beidou navigation in location service metadata.
