Master control system for satellite image processing

A system, comprising:

• a master control management module, a first field programmable gate array (FPGA) module, and a second FPGA module;
• wherein:
• the master control management module is in connection and communication with the first FPGA module, the second FPGA module, and a housekeeping computer;
• the first FPGA module is in connection and communication with the second FPGA module and a remote-sensing satellite image processing device;
• the master control management module is adapted to perform assignment of tasks, the tasks comprising state monitoring of the remote-sensing satellite image processing device, state feedback of the remote-sensing satellite image processing device, command receiving and parsing, fault-tolerance emergency processing, region division and temporal phase determination, satellite attitude estimation, and working/standby modes;
• the first FPGA module is adapted to communicate with a processor in the satellite image processing device, monitor an operation state of the satellite image processing device, send operation state information of the satellite image processing device to the master control management module, receive a task assignment command issued by the master control management module, and transmit the task assignment command to the satellite image processing device;
• the second FPGA module is adapted to determine positions of stars in an image, and send the positions of the stars in the image to the master control management module, so that the master control management module determines a visual axis pointing direction of a sensor in the image processing device, according to the positions of the stars in the image;
• and
• the master control management module is further adapted to determine priorities of the tasks, and to design a communication interface and a communication protocol suitable for a satellite environment.
