The invention discloses a space-time grid-based low-orbit access selection method and a storage medium. The method comprises the steps of establishing a low-orbit satellite network multi-scale grid and a grid attribute matrix; after the service initiates an access application, extracting information carried by the service application; for deterministic services, a satellite with the most idle channels is selected for access, and if no idle channel exists, occupied channels are selected for preemptive access; updating a space-time grid attribute matrix after access; for non-deterministic services, a satellite with the most idle channels is selected for access, the space-time grid attribute matrix is updated after access, and if no idle channel exists, the service application is stored in a corresponding cache queue to wait for the idle channel; and if the service application waiting time in the queue exceeds a threshold value, refusing service access. According to the ground coverage area ...
