Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile positioning technologies face challenges in achieving high-precision positioning with efficient resource utilization, particularly in establishing a positioning network that can cover a large number of users with minimal investment in base stations.
Innovation Solution
A method and apparatus for establishing a positioning system that gradually forms a network through single-baseline RTK, allowing for efficient coverage of more users with fewer base stations. This is achieved by connecting new nodes to established nodes based on distance criteria, determining sub-networks, and forming virtual base stations for mobile stations.

Engineering Contradiction Analysis
1Area of stationary object
If a traditional positioning network is established to cover more users, then the coverage area increases, but the number of base stations and investment cost increase significantly
Solution Approach 1:
The positioning network is divided into multiple sub-networks, each serving a specific regional area. This segmentation allows the system to expand coverage by creating smaller, manageable sub-networks rather than attempting to establish a single large network, thereby reducing the number of base stations needed while maintaining comprehensive coverage.
Solution Approach 2:
The patent introduces a server as an intermediary component that manages the positioning networks. The server receives positioning requests, determines appropriate sub-networks, and provides positioning data to user equipment. This intermediary enables efficient resource utilization and reduces the need for direct base station connections to all users.
2Measurement precision
If more base stations are deployed to provide high-precision positioning, then positioning accuracy is maintained, but the investment cost increases
Solution Approach 1:
By segmenting the network into sub-networks, the system maintains positioning accuracy within each regional sub-network while reducing the overall number of base stations required. Each sub-network can be optimized for local accuracy requirements without requiring base stations across the entire service area.
Solution Approach 2:
The patent implements local quality by creating sub-networks tailored to specific regional requirements. Each sub-network is designed to meet the positioning accuracy needs of its specific area, allowing the system to allocate base stations strategically where they are most needed rather than uniformly across all regions.
3Adaptability or versatility
If a positioning network is established to serve more users, then user coverage increases, but the system complexity increases
Solution Approach 1:
The system segments the user base into different sub-networks based on their geographical locations and requirements. This segmentation simplifies system management by dividing the complex task of serving all users into smaller, manageable sub-networks, each with its own set of base stations and configuration parameters.
Solution Approach 2:
The server acts as an intermediary that manages the complexity of user coverage. It receives positioning requests from user equipment, determines which sub-network should serve the user based on their location, and routes the appropriate positioning data. This intermediary layer abstracts the complexity from individual base stations and simplifies the overall system architecture.
Data Source
AI summary
The present disclosure relates to a method and an apparatus for establishing a positioning network. The positioning network includes a data processing center and at least one reference station, and one node in the positioning network represents one reference station. The method includes: determining, if a first historical positioning network capable of forming a new positioning network with a newly added node exists in a network list of the data processing center, whether the newly added node forms the new positioning network with the first historical positioning network; and determining, if the network list does not exist in the data processing center, whether the newly added node is capable of forming a new positioning network with nodes in a first node information list. Before network real-time kinematic (RTK) is formed, a user can use a single-baseline RTK positioning service. The network RTK is formed once a networking condition is met. A positioning network is gradually established, requirements of users may be satisfied with less investment when there are fewer users in the early stage, and the network is gradually formed with the increase of users, so that more users can be covered by using fewer base stations.
