This paper presents a method to improve the storage efficiency of massive satellite data. Through analyzing the influencing factors such as observation target

data quality

access frequency and management overhead

the evaluation model of satellite data is obtained

which can accurately guide the storage of satellite data and improve the satellite data input The accuracy of the library

the quality of the satellite data storage. According to the minimum data transmission granularity and the digital characteristics of the intensity of the satellite data

a better performance satellite data warehousing transmission link is selected to improve the efficiency of satellite data storage and improve the storage efficiency of massive satellite data. Experimental results show that satellite data storage efficiency is high

storage quality is high

and storage accuracy is high when the proposed method is used to store massive satellite data.
