Solution Overview
Problem
Current satellite communications systems are not designed to handle non-compliant antennas, requiring time-consuming interference analysis and specialized knowledge, which limits their use and flexibility, especially for end users.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite operators perform detailed interference analysis for non-compliant antennas, then transmission safety is improved, but time consumption and operational complexity increase
Solution Approach 1:
The system pre-calculates and stores interference data in a coordination database before actual transmission occurs. The database contains pre-computed interference information for various antenna configurations and satellite positions, allowing operators to quickly query results without performing time-consuming real-time calculations.
Solution Approach 2:
An automated interference analysis system acts as an intermediary between non-compliant antenna users and satellite operators. This system performs the detailed interference calculations using the coordination database and presents simplified results to users, eliminating the need for operators to conduct manual analysis for each transmission request.
2Reliability
If satellite operators coordinate non-compliant terminals using standard antenna envelopes, then interference protection is improved, but adaptability to specific antenna configurations deteriorates
Solution Approach 1:
The system transitions from using generic standard antenna envelopes to storing and querying specific interference data for each individual antenna configuration. The coordination database contains tailored interference information matched to specific antenna characteristics, satellite positions, and frequency bands, providing locally optimized interference protection rather than blanket restrictions.
Solution Approach 2:
The system dynamically adjusts coordination parameters based on specific antenna characteristics stored in the database. Instead of applying fixed standard envelope constraints, the system queries the database for interference data matching the actual antenna parameters (gain patterns, beam widths, frequencies) and applies coordinated transmission parameters accordingly.
3Device complexity
If end users perform interference analysis themselves, then device complexity is reduced, but measurement precision and analysis accuracy deteriorate
Solution Approach 1:
The system provides end users with access to pre-computed, high-precision interference data through the coordination database via automated queries. Users simply input their antenna parameters and desired transmission conditions, and the system retrieves accurate interference analysis results from the database, combining user simplicity with expert-level analysis precision.
