Problems solved by technology

Although the test system can perform semi-physical simulation of satellite attitude control, the cost is high, and the information flow is complicated, so the reliability and safety quality of the simulation are difficult to guarantee
In addition, the simulation system is completely separated from the test of each component, and the test results of the components are not well applied, which increases the test cycle

Embodiment Construction

[0035] As shown in Figure 2, the present invention comprises three parts of component-level simulation test, system-level digital simulation test and system-level semi-physical simulation test, wherein component-level simulation test and system-level digital simulation test are provided for system-level semi-physical simulation test. Based on physical data, system-level semi-physical simulation effectively utilizes the database of component-level simulation tests and the test results of system-level digital simulation for semi-physical simulation.

[0036]All the above tests are carried out through the satellite Internet. Before the test, the on-board control equipment, ground dynamics simulation equipment, measurement components, and execution components are respectively connected to the star Internet through the bus interface, connected through the star Internet, and Star Internet for information exchange and control. Star Internet is a completely independent dual redundant ...
