英文摘要：

According to the challenge of storage and processing faced by large-scale GNSS network, the GNSS distributed storage and processing architecture from infrastructure, data management, computing and service to application is designed. Firstly, based on HDFS, the storage directory is improved. Secondly, based on HBase, the table architecture is designed. Thirdly, based on MapReduce, sub-network distributed processing is proposed. The distributed platform is built in the experiment, and the distributed storage, parallel retrial, publication and distributed processing are achieved. The performances of storage and computing are significantly improved. The result shows that the method proposed by this paper can be applied to the storage and computing of large network.
