The present invention is applicable to the technical field of
simulation, and provides a
simulation method and apparatus of a space-ground
integrated management system. The method comprises the steps of receiving
simulation configuration parameters, and selecting a corresponding simulation sub-
system according to the simulation configuration parameters, wherein the simulation sub-
system comprises at least one of a
constellation simulation system, a physical
link layer simulation system, a star-earth inter-star channel
simulation system, and a communication protocol simulation
system, and the
constellation simulation system, the physical
link layer simulation system, the star-earth inter-star channel simulation system, and the communication protocol simulation system are connected with each other by using RTI interfaces and perform
data transmission; and building a corresponding simulation model for the selected simulation sub-system, and performing simulation by using the simulation model. Through adoption of the method, integrated management and simulation can be performed on the
physical layer link, the communication protocol and the
constellation, simulation
verification can be performed on the
satellite communication system and the
data acquisition system, and the method supports research and development of multiple
satellite communication systems and
data acquisition systems.
