Satellite dynamic and control distributed simulation platform

Abstract

The invention discloses a satellite dynamic and control distributed simulation platform, which belongs to the technical field of satellite control and simulation. The satellite dynamic and control distributed simulation platform is characterized by being constructed on the basis of various spatial environment models, dynamic models and task requirement analysis, wherein the platform consists of six pieces of main equipment, which are a network switch, an SIM tool kit (STK) track computer, a gesture and track dynamic computer, a control algorithm computer, a curve display computer and a simulation management computer respectively; and the personal computers (PC) are connected through network cables and communicate according to a user datagram protocol (UDP) or transmission control protocol / internet protocol (TCP / IP) protocol. The platform has the effect and advantage of supporting full task period and multidisciplinary design, development and simulation verification from flight task making to simulation verification result output.

Description

technical field [0001] The invention belongs to the technical field of satellite control and simulation, and constructs a distributed simulation platform for satellite dynamics and control. Background technique [0002] With the rapid development of space militarization and commercialization, outer space has become a strategic "commanding height" for safeguarding national security and interests. Space-based systems composed of various satellites will be widely used in remote sensing reconnaissance, special communications, electronic reconnaissance and offensive and defensive confrontation, and become an important part of aerospace military equipment. The development of my country's aerospace military equipment urgently needs all kinds of high-performance military satellites. However, due to our national strength, it is impossible to take the path of large investment and large output. We must innovate in design and development methods in order to achieve more with less invest...

Problems solved by technology

At present, the modeling and simulation of space vehicles is still limited to the sub-system level and single discipline, and rarely involves the modeling and simulation of the whole system, let alone the research on the coupling relationship between multiple disciplines and disciplines. It is difficult to achieve flexibility among systems. , rapid joint modeling and simulation, which restricts the further improvement of the reliability of the simulation system

[0005] The digital design of the digital space vehicle is the basis and core content of this project. The space vehicle is a complex system composed of structure, electronics, control, software, communication, power supply and other subsystems. Therefore, one of the ways to design the digital space vehicle is to use the unified The modeling language and environment of the space vehicle are used to digitally model the key characteristics of the multi-domain. This method is conducive to interdisciplinary impact analysis and system-wide simulation. However, there is no mature commercial software available so far, and it is impossible to inherit the existing Some research basis
