The invention provides a distributed
simulation system for deep space multi-
relay satellite communication. The
system employs a
structure based on a high-level architecture (HLA) standard and has
reusability and
interoperability; the
system can realize data communication among multiple protocols and different
simulation system platforms, and solves the problems of incapability of identifying data among the different protocols and non-standardized interfaces of
simulation systems; the system can realize real-time and real transmission of each data packet, the transmission effects are obvious, and the performance analysis is high; through externally connected
software, real transmission scenes can be simulated, and real-time dynamic communication environment data is provided; through two
relay federal members, multiple relays are simulated and multi-node segment
data transmission for a deep space DTN is demonstrated, and through multi-
relay multi-hop segment transmission, transmission efficiency in a deep space long distance and long time
delay environment is improved; and an acquisition scheduling module is taken as a control center of a simulation platform, on one hand, real-time related data of current simulation platform operation is acquired and displayed in real time, and on the other hand, effective analysis can be performed on acquired data, and related decisions are made. The
simulation system provided by the invention has three characteristics of interrupted connection, storage forwarding and keep transmission, thereby being well adaptive to the transmission characteristics of a space DTN.
