Satellite Attitude Control Simulator Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite attitude control systems face challenges in accurately predicting and verifying satellite attitude control performance, leading to potential unsafe mode transitions and manual intervention, especially when actual satellite operations deviate from predicted attitudes.
Innovation Solution
A method and apparatus that generate and transmit satellite task execution commands based on simulation results from a satellite attitude control simulator, allowing for real-time comparison and adjustment of commands to ensure operations stay within predetermined ranges, thereby enhancing predictive reliability and reducing manual interventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite attitude control is verified using a simulator and ground observation post, then predictive capability is improved, but system complexity increases
Solution Approach 1:
The patent combines the simulator and ground observation post into an integrated verification system where the simulator generates predicted attitude data and the ground observation post provides actual measurement data, which are then automatically compared to verify satellite attitude control performance without requiring separate manual analysis processes
Solution Approach 2:
The verification system serves multiple functions: it simulates satellite attitude control, measures actual attitude through ground observation, compares predicted versus actual performance, and provides automated verification - replacing multiple separate tools and processes with a single multi-functional system
2Reliability
If manual intervention is used when satellite deviates from predicted attitude, then operational safety is improved, but operational efficiency deteriorates
Solution Approach 1:
The system implements automated feedback by continuously comparing actual satellite attitude measurements with predicted attitude data from the simulator. When deviations are detected, the system automatically generates verification results and alerts, eliminating the need for manual monitoring while maintaining safety through systematic comparison and automated response protocols

AI summary
Provided is a method of comparing satellite attitude control performances, the method including generating, by a controller, a satellite task execution command, receiving, by an input and output (I/O) unit, a result of a simulation performed on a satellite attitude control by a satellite attitude control simulator based on the satellite task execution command, and transmitting, by the I/O unit, the satellite task execution command to a satellite based on the result of the simulation.
