Problems solved by technology

However, the xPC Target / Simulink Real-Time operation process is cumbersome, data observation is inconvenient, parameter setting is complicated, and the progress of simulation debugging is severely restricted

Although xPC Target / Simulink Real-Time provides a rich library of I / O driver devices for standard I / O boards, it involves the use of special data acquisition and communication boards, requiring self-written drivers, which undoubtedly increases unnecessary workload. For example, the RS422 serial port card supported by xPC Target / Simulink Real-Time is limited

Moreover, although traditional attitude and orbit control simulation tests can judge the operating status of satellites through observation data, the integration level is greatly reduced when multi-faceted data linkage is involved, and additional calculations are often involved, which increases the repetitive workload and cannot be realistic.
