Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a unified wide-area service architecture is adopted, then service coverage is improved, but positioning service quality deteriorates in local scenarios
Solution Approach 1:
The patent segments the positioning service system into multiple edge cloud servers, each responsible for a specific local service area. This allows the system to maintain wide-area coverage through multiple segmented units while providing high-precision positioning services tailored to each local area's specific requirements.
Solution Approach 2:
The patent implements local quality by deploying edge cloud servers that provide customized positioning services for different service areas. Each edge cloud server can be configured with local reference station data and parameters specific to its service area, enabling optimized positioning performance for local scenarios such as mining areas, forest areas, and urban environments.
2Area of stationary object
If a unified wide-area service architecture is adopted, then service coverage is improved, but construction and maintenance costs increase
Solution Approach 1:
The system divides the wide-area positioning service into multiple independent edge cloud servers, each handling a specific local area. This segmentation allows for modular construction and maintenance, where each edge cloud server can be independently deployed, configured, and maintained, reducing the overall complexity and cost compared to a monolithic wide-area system.
Solution Approach 2:
The edge cloud server acts as an intermediary between the user terminal and the reference station network. It receives satellite positioning information from terminals, applies local correction data, and returns positioning results. This intermediary layer simplifies the architecture by localizing processing tasks and reducing direct communication requirements between terminals and the central system.
3Device complexity
If satellite positioning information is processed centrally, then system complexity is reduced, but positioning precision deteriorates
Solution Approach 1:
The edge cloud server serves as an intermediary that performs local positioning calculations using satellite positioning information from terminals and local correction data from reference stations. This distributed intermediary approach maintains system simplicity while improving precision by processing data closer to the source and applying location-specific corrections.
Solution Approach 2:
The patent introduces a new dimensional layer in the positioning architecture by deploying edge cloud servers at the network edge, between the user terminals and the central reference station network. This additional dimension enables localized processing and correction application, improving precision without significantly increasing overall system complexity.

AI summary
A user terminal positioning method is used in an edge cloud server, and includes: receiving satellite positioning information sent by a user terminal; determining a location service area in which the user terminal is located; on the basis of the location service area, acquiring a differential correction model corresponding to the location service area from a public cloud server; using the satellite positioning information and the differential correction model to implement location calculation to obtain location information of the user terminal; and sending the location information to the user terminal.
