Engineering Contradiction Analysis
1Speed
If electromagnetic waves in high frequency band are used for satellite communication, then communication speed is improved, but communication reliability deteriorates due to atmospheric interference
Solution Approach 1:
The system performs preliminary measurement of communication environment parameters (temperature, humidity, pressure, electromagnetic wave characteristics) before actual communication occurs. Based on these measurements, it predicts the communication speed in advance and sets appropriate communication parameters, thereby preparing the system to handle atmospheric interference before it degrades communication reliability.
Solution Approach 2:
The system continuously measures actual communication environment parameters during communication and compares them with reference values. Based on this feedback, it dynamically adjusts communication parameters to maintain optimal communication speed while compensating for atmospheric interference effects.
2Stability of the object's composition
If time slots are reserved in advance for satellite communication, then system stability is improved, but communication efficiency deteriorates due to inability to adapt to real-time environmental changes
Solution Approach 1:
The system maintains the stable time slot reservation structure but introduces dynamic adjustment of communication parameters within each time slot. By measuring environment parameters and predicting communication speed in real time, the system adapts communication settings dynamically while preserving the overall scheduled structure, thus balancing stability with efficiency.
3Measurement precision
If correlation analysis of orbital information is performed, then communication speed prediction accuracy is improved, but computational complexity increases
Solution Approach 1:
The system segments the correlation analysis into multiple independent components: orbital parameter analysis, environment parameter analysis, and communication speed prediction. Each component processes specific data separately and combines results, reducing overall computational complexity while maintaining prediction accuracy through modular analysis.
