1Area of stationary object
If satellite-based positioning systems are used, then global coverage is achieved, but signal strength varies and positioning precision deteriorates in terrestrial environments
Solution Approach 1:
The patent segments the positioning system into satellite-based component and terrestrial component (5G network infrastructure). The satellite system provides global coverage while the terrestrial 5G system provides high-precision positioning in specific areas, allowing each segment to optimize for its intended function without compromising the other.
Solution Approach 2:
The patent introduces terrestrial 5G network infrastructure as an intermediary between satellite-based positioning and end devices. This intermediary enhances positioning precision in terrestrial environments by providing localized reference signals and timing information that supplement satellite signals, thereby resolving the precision deterioration issue in ground-based applications.
2Measurement precision
If terrestrial positioning techniques are used, then positioning precision is improved, but coverage continuity deteriorates in remote areas
Solution Approach 1:
The patent merges satellite-based positioning and terrestrial 5G positioning into a hybrid system. This combination allows the system to leverage satellite coverage for global continuity while utilizing terrestrial infrastructure for high-precision positioning, thereby achieving both continuous coverage and high precision across diverse environments including remote areas.
Solution Approach 2:
The patent creates a universal positioning system that can operate in both satellite-dependent and satellite-independent modes. The system adapts its function based on availability of infrastructure: using satellite signals in remote areas for continuous coverage, and switching to or augmenting with terrestrial 5G signals in areas with network infrastructure for enhanced precision, thus achieving multi-functional capability.
3Reliability
If hybrid satellite-terrestrial systems are implemented, then positioning reliability is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the positioning system automatically selects and switches between satellite-based and terrestrial 5G-based positioning methods based on signal availability and quality. This automated selection process reduces the need for complex manual configuration and management, thereby improving reliability while minimizing the operational complexity burden on users and operators.
4Measurement precision
If 5G NR infrastructure is used for positioning, then positioning precision is improved, but infrastructure requirements increase
Solution Approach 1:
The patent leverages the multi-functionality of 5G NR infrastructure, which serves both communication and positioning purposes simultaneously. By using the same network infrastructure for both data transmission and positioning signals, the system achieves high positioning precision without requiring separate dedicated positioning infrastructure, thereby avoiding the need to increase infrastructure quantity.
