Description

technical field

[0001] The invention relates to the technical field of "Geodesy and Surveying Engineering" in the discipline of "Surveying and Mapping Science and Technology", in particular to a cloud storage method for massive GNSS small files. Background technique

[0002] With the continuous development of science and technology, the global, national and regional continuous operating reference station network (CORS, Continuously Operating Reference Station System) has been continuously built, and the Global Navigation Satellite System (GNSS, Global Navigation Satellite System) is widely used in various fields , especially the continuous networking and continuous observation of the joint CORS with more reference stations and higher levels formed by the integration of independent CORS, the data volume of the global satellite navigation system is getting larger and larger.

[0003] Massive data brings challenges to storage and management, and a large amount of data above ter...
