Space operation and control big data storage method based on space-time grid

The invention discloses an aerospace operation and control big data storage method based on a space-time grid, relates to the technical field of remote sensing satellite operation and control data storage, and mainly relates to application of organization and management of remote sensing satellite operation and control big data, remote sensing satellite task planning and the like. The method comprises the following steps: firstly, dividing the earth into continuous, non-overlapping and full-coverage unit grids according to an earth subdivision grid theory method, coding the grids according to a certain logic rule, and providing a basic framework for subsequent space-time grid construction; satellite resource information and geographic space information are stored in corresponding geographic grids by predicting and calculating satellite operation orbits and meteorological data, and time dimension information is attached to the geographic grids. When a user puts forward observation requirements, the grids and t
