AI Technical Summary

Problems solved by technology

However, the existing satellite simulation test system is generally only designed for specific satellite platforms, and has the following technical deficiencies: 1) the simulation test system is complex, costly, large in size, and difficult to maintain; The computer and the simulation test system also need to carry out corresponding hardware and / or software modifications; 3) The simulation test system is highly coupled, so it is not easy to expand; 4) The function of the simulation test is relatively single and the simulation effect is limited; 5) During the test, the hardware and software structure of the satellite platform needs to be adapted accordingly, and the satellite is not completely in the real operating condition, etc.
However, the satellite-ground closed-loop test system still has the following technical deficiencies: the system is mainly based on special acquisition cards such as "serial port card" and "1553B board card" to collect specific types of bus data and send the data to the dynamic computer for simulation. If the platform changes, such as the type or number of buses used by satellite components changes, the system needs to add corresponding acquisition cards and modify the host computer simulation software on the dynamics computer, that is, the system is not very versatile and expandable
