Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing positioning systems using GNSS require high arithmetic capability for data analysis, leading to inefficiencies when positioning data is not satisfactory, necessitating repeated data acquisition and reducing overall efficiency.
Innovation Solution
A positioning system with a receiving terminal and an arithmetic processor that stores and analyzes positioning data, allowing for continuous data acquisition and analysis, with a good-or-poor determining section to assess data quality and a movement detection section to cancel positioning if the terminal is moved, optimizing data usage and reducing duplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning data is transmitted to an arithmetic processor for analysis, then positioning accuracy is improved, but when the analysis result is poor, positioning data acquisition must be repeated from the beginning, reducing工作效率
Solution Approach 1:
The system performs preliminary actions by continuously acquiring and storing positioning data before analysis is completed. When analysis results are poor, the previously acquired data is already available for re-analysis without requiring re-acquisition, thus maintaining positioning accuracy while improving efficiency.
Solution Approach 2:
The arithmetic processor provides feedback to the GPS receiver about the quality of positioning data analysis results. This feedback mechanism allows the system to understand whether the acquired data is satisfactory and triggers appropriate actions (re-acquisition or continuation) accordingly, resolving the contradiction between accuracy and efficiency.
2Productivity
If positioning data is continuously acquired and accumulated, then positioning efficiency is improved, but data storage requirements and system complexity increase
Solution Approach 1:
The GPS receiver acts as an intermediary with built-in storage capability between the satellite signal source and the arithmetic processor. This intermediary function allows continuous data accumulation without requiring complex distributed storage systems, improving efficiency while controlling system complexity.

AI summary
In a positioning system, an arithmetic processor analyzes positioning data acquired by a receiving terminal and determines a positioning target location. Upon reception of positioning data, the arithmetic processor accumulates the positioning data on analysis data stored in a storage section prior to the reception, stores an accumulated data as new analysis data, and transmits an analysis result to the receiving terminal. The receiving terminal transmits positioning data, acquired for a predetermined time, to the arithmetic processor and continues to acquire positioning data. Upon reception of the analysis result, the receiving terminal determines whether the analysis result is good or poor. When the analysis result is poor and the positioning data is stored for the predetermined time from a last transmission of the positioning data, the receiving terminal transmits the positioning data to the arithmetic processor and continues to acquire positioning data. If the analysis result is good, the receiving terminal completes positioning of the positioning target location.
