Storage and calculation integrated design method for space navigation

The invention relates to the technical field of data calculation and storage, and provides a storage and calculation integrated design method for space navigation, which comprises the following steps: S1, FPGA (Field Programmable Gate Array) codes in a solid memory module are burnt in a PROM (Programmable Read Only Memory) of a spaceborne computer, and the solid memory module is used for storing load data received by an aircraft; s2, when the spaceborne computer is powered on and started, the FPGA in the solid memory module is loaded and started in a DMA mode, and verification is carried out after loading is completed; s3, the working states of the spaceborne computer and the external load single machine are processed by the CPU, written into FLASH in the solid memory module and sent to a data transmission single machine in the external load single machine at regular time, and the working states are load data; and S4, the on-board computer reads the storage space recording the load data in the solid storage m
