1Volume of moving object
If wireless communication technologies are used for BVLOS operations of UAVs, then UAV operation range is extended, but connectivity reliability deteriorates due to dynamic network conditions and signal strength variations
Solution Approach 1:
The system performs preliminary actions by continuously measuring connectivity parameters (signal strength, signal-to-noise ratio, bit error rate) and comparing them against predicted values before critical failures occur. This advance detection allows the UAV to take preventive measures such as adjusting flight path or switching communication channels before connectivity is lost, thereby maintaining reliability while extending operation range.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring actual connectivity measurements and comparing them with predicted connectivity values. When deviations exceed thresholds, the system generates warnings and adjusts UAV operations accordingly. This closed-loop feedback ensures connectivity reliability is maintained even as UAV operation range is extended into areas with more variable network conditions.
2Reliability
If connectivity measurements are continuously monitored to detect anomalies, then safety is improved, but system complexity increases due to additional monitoring and processing requirements
Solution Approach 1:
The UAV performs self-service by autonomously conducting connectivity measurements and comparing results with predicted values using its own onboard processors. The system automatically generates warnings when anomalies are detected and can independently adjust its flight path or communication parameters without requiring complex external monitoring infrastructure, thereby improving safety while minimizing additional system complexity.
Solution Approach 2:
The system monitors changes in connectivity parameters (signal strength, signal-to-noise ratio, bit error rate) and uses these parameter variations to detect anomalies. By focusing on specific key parameters rather than comprehensive system monitoring, the approach achieves enhanced safety through anomaly detection while keeping the monitoring and processing requirements manageable.
3Productivity
If predicted coverage data is used to guide UAV flight paths, then navigation efficiency is improved, but measurement precision deteriorates due to inaccuracies in predicted network coverage
Solution Approach 1:
The system performs preliminary connectivity measurements at various locations before UAV navigation to build and update predicted coverage maps. These advance measurements allow the system to create more accurate connectivity predictions that reflect actual network conditions, thereby improving both navigation efficiency and measurement precision simultaneously.
Solution Approach 2:
The system uses feedback from actual connectivity measurements during UAV operations to continuously refine and update predicted coverage data. By comparing measured connectivity values with predicted values and using these differences to adjust future predictions, the system improves measurement precision over time while maintaining navigation efficiency through reliable predicted coverage guidance.
