摘要：In order to meet the increasingly complex on-orbit data processing tasks in satellite embedded systems and to achieve standardized management of spatial data access, this paper integrates the existing UnQLite small-scale embedded database system based on the full consideration of the memory and performance of the on-board hardware platform. A database migration method for the BM3803 embedded processor is proposed. This method can omit the overhead caused by the operating system, the specific porting work is completed, and some of the source code implementation procedures are illustrated. After testing and verification, this method is correct and feasible. At the same time, it provides new solutions for data management related technologies in embedded systems in space.
