Platform
Introduction
The satellite attitude orbit control real-time
simulation system is a lab test method for simulating satellites’ orbit
movements. It is usually used to verify satellite control system plans and
performance indicators. In this system, the satellite attitude control
real-time simulation system consists of two real-time simulators: satellite-borne
computer real-time simulator and crosslinking-environment real-time simulator.
The satellite-borne computer real-time simulator is used to simulate the AOCC
on satellites and realize satellite attitude control and orbit control; the
crosslinking-environment real-time simulator is used to simulate the satellite
attitude control execution mechanism, satellite dynamics and typical control
loops of sensors, as shown in the following figure
2. Platform Features
-
Prototype Verification: In the advanced
aerospace engineering field, the cost of developing satellites is very high,
and the development period is very short. With the establishment of this platform,
users can start to perform prototype simulation verification of satellite-borne
computers in the early stage of plan design.
-
Normal Operating Condition Test: In order
to test the real-time performance of the software and hardware of
satellite-borne computers, an external real-time simulation environment of
satellite-borne computers needs to form a loop with satellite-borne computers.
This external simulation environment should be able to correctly and flexibly
simulate, in real time, satellite motions, attitude sensors, execution
mechanisms, various faults and boundary conditions, etc. If you use a special
simulator to test satellite-borne computer software and hardware, it will be
very time-consuming and inflexible. This platform can simulate such an external
environment in a swift and low-cost manner.
-
Abnormal Status Simulation: Besides testing
satellite-borne computer software and hardware in normal status, you also need
to simulate abnormal status to check whether satellite computers can effectively
and promptly handle abnormalities.
