Description

Technical Field

[0001] The invention belongs to the technical field of application of computer technology in remote sensing satellite data processing systems, and in particular relates to a method for facilitating remote sensing satellite data archiving and recovery performance testing. Background Art

[0002] In order to meet the needs of users from all walks of life for remote sensing satellite data, many new remote sensing satellites are launched every year, so the ground system processes, archives and distributes a large amount of remote sensing satellite data every day. At the same time, before the ground processing system is delivered to users, it is generally necessary to conduct at least 3 months of on-orbit testing. In addition to testing whether the quality of satellite images meets the overall development requirements, it is also necessary to test whether the efficiency of ground system processing, archiving and distribution meets the design requirements. The performance test of the archiving system mainly includes two aspects. One is to migrate all level 0 and product data produced by the processing system that day from online storage to near-line tape libraries within the specified time every night, and the other is to restore the data stored in the near-line tape library to the designated location of online storage in a timely manner.

[0003] At present, a remote sensing satellite ground processing system has the ability to comprehensively process, archive and distribute multiple satellites, so there is a long-term state of business operation and on-orbit testing being carried out simultaneously. For the archiving system, the recovery task generally has a higher priority than the archiving task. When there are a large number of recovery tasks that need to extract level 0 or product data from the near-line tape library in the archiving system, a large amount of tape library resources will be occupied first, resulting in a large number of business archiving tasks waiting in line. If the on-orbit test of the data archiving and recovery performance of the ground system of the newly launched satellite is carried out at the same time, it is bound to cause interference between business operation and test tasks, affecting both the efficiency of business operation and the authenticity of test indicators. Summary of the invention
