Aiming at the problem that the current remote sensing satellite Charge Couple Device (CCD) camera has an increasing width and speed, and the output bandwidth of existing camera simulator is insufficient, an Non-Volatile Memory express(NVMe) based ultrahigh-speed multi-channel remote sensing camera simulator is proposed and implemented. This simulator employs a Field Programmable Gate Array(FPGA) to implement four groups of NVMe SSD host controllers and complete the read and write operations on the Solid State Drive(SSD). The Direct Memory Access(DMA) controller is utilized to read the cache data in DDR4, and the data is output through the optical fiber interface after being encapsulated. Experimental results show that the average write rate of the NVMe host controller can reach 1.7 GBps, and the average read rate can reach 3.2 GBps. The overall storage capacity of the simulator is 8 TB, the external output bandwidth is up to 80 Gbps, and it supports eight-way optical fiber interface outputs. This simulator with strong stability and good scalability, has been successfully applied in a remote sensing satellite CCD camera simulator system, which provides sufficient guarantee for the testing and debugging of device such as data transmission.
