Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing positioning systems, such as GPS, struggle to determine the precise position of a mobile communication device relative to a specified destination while maintaining predetermined accuracy, especially when intermediate targets are involved, due to limitations in measurement planning and data collection.
Innovation Solution
A method and system that create and evaluate measurement plans to determine the position of a mobile communication device by using a GNSS receiver, collecting position and observation information, and applying optimization algorithms to ensure the desired accuracy is achieved at the main and intermediate geographical targets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS positioning is used to determine position, then position information can be obtained, but the positional accuracy is insufficient to meet predetermined accuracy requirements
Solution Approach 1:
The patent segments the positioning task into multiple measurement plans, each targeting specific intermediate geographical points along the navigation route. By dividing the overall journey into segments with dedicated measurement plans, the system can accumulate positional information more accurately than a single GPS reading, thereby resolving the contradiction between obtaining position information and achieving predetermined accuracy requirements.
Solution Approach 2:
The patent creates and evaluates measurement plans in advance before actual navigation. The system pre-calculates optimal measurement points, selects appropriate communication devices for measurements, and prepares observation information collection strategies beforehand. This preliminary action ensures that when navigation occurs, the positional accuracy requirements can be met through pre-planned measurement sequences rather than relying solely on real-time GPS accuracy.
2Measurement precision
If multiple measurements are taken to improve accuracy, then positional precision increases, but the complexity of measurement planning and data collection increases
Solution Approach 1:
The patent incorporates feedback mechanisms where measurement plans are created, evaluated for feasibility, and refined based on evaluation results. The system assesses whether planned measurements can achieve desired accuracy, selects appropriate communication devices, and adjusts the measurement plan accordingly. This feedback loop automates the complexity management, allowing multiple measurements to be coordinated systematically rather than manually, thereby resolving the contradiction between improved precision and increased planning complexity.
Solution Approach 2:
The system automatically performs measurement plan creation, evaluation, and optimization without requiring manual intervention. The automated processes include selecting communication devices, determining measurement sequences, evaluating feasibility, and adjusting plans based on expected outcomes. This self-service approach handles the inherent complexity of multi-measurement coordination through automation, allowing the system to achieve high positional accuracy without proportionally increasing operational complexity.
3Measurement precision
If measurement plans are created and evaluated before execution, then positional accuracy can be ensured, but the time required for planning and preparation increases
Solution Approach 1:
The patent performs measurement plan creation and evaluation in advance during off-navigation periods. The system pre-calculates measurement sequences, selects communication devices, and prepares observation strategies before actual navigation begins. This preliminary action shifts the time investment to before navigation, allowing real-time execution to proceed efficiently while still achieving predetermined accuracy requirements through pre-planned measurements.
Solution Approach 2:
The system dynamically adjusts measurement plan parameters such as the number of measurements, selection of communication devices, and observation information types based on navigation requirements and available resources. By optimizing these parameters in advance, the system achieves the minimum necessary planning time while ensuring positional accuracy requirements are met during actual navigation execution.
